ZMDI ZSPM401xB Synchronous Buck Converters

ZMDI ZSPM401xB High Efficiency Synchronous Buck Converters are DC/DC synchronous switching regulators with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 1MHz enables the use of small filter components, resulting in reduced board space and reduced BOM costs. These ZMDI devices come in 1A (ZSPM4011B), 2A (ZSPM4012B), and 3A (ZSPM4013B) rated continuous output current ratings. The ZSPM401xB family utilizes current mode feedback in normal regulation PWM mode.  When the regulator is disabled (EN is low), the device draws less than 10uA quiescent current. The ZSPM401xB family integrates a wide range of protection circuitry, including: input supply under-voltage lockout, output voltage soft start, current limit, and thermal shutdown. ZSPM401xB devices include supervisory reporting through the PG (Power Good) open drain output to interface other components in the system.

ZMDI ZSSC3036 16-Bit Sensor Signal Conditioner IC

ZMDI ZSSC3036 16-Bit Sensor Signal Conditioner (SSC) IC is designed for high-accuracy amplification and analog-digital conversion of a differential input signal. ZMDI ZSSC3036 is intended for high-resolution altimeter module applications and can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, this SSC can also provide a corrected temperature output measured with an internal sensor. ZSSC3036 provides accelerated signal processing in order to support high-speed control, safety, and real-time sensing applications. It complements other ZMDI ZSSC30x6 devices.

ZMDI ZSPM4121 Battery Management Load Switch

ZMDI's ZSPM4121 Battery Management Load Switch can be used to protect a battery from excessive discharge. It actively switches the battery power source off if it drops to a set threshold (Off Mode). When the input battery voltage is above the threshold, the load switch is on (On Mode). The ZSPM4121 threshold voltage (VTHRESH) is programmed at manufacturing to a set point in the range of 1.2V to 4.2V with 100mV steps between options. When the input battery voltage has been switched off by the ZSPM4121, the quiescent current draw on the battery is in the order of 100pA (typical). The ZSPM4121 consists of an internally generated threshold voltage, a comparator with hysteresis, slew rate control for the load switch, a P-channel load switch, and an open-drain indicator pin.

ZMDI ZSPM9000 Ultra-Compact High-Performance DrMOS Powerstage

ZMDI's ZSPM9000 Ultra-Compact High-Performance DrMOS Powerstage is a fully optimized, integrated MOSFET plus driver powerstage solution for high-current, high-frequency, synchronous buck DC-DC applications. The device incorporates a driver IC, two power MOSFETs, and a bootstrap Schottky diode in a thermally enhanced, ultra-compact 6mmx6mm PQFN40 package. With an integrated approach, the ZSPM9000's complete switching power stage is optimized for driver and MOSFET dynamic performance, system inductance, and power MOSFET RDS(ON). It uses innovative high-performance MOSFET technology, which dramatically reduces switch ringing, eliminating the snubber circuit in most buck converter applications.

ZMDI ZSSC3026 Low Power 16-Bit Sensor Signal Conditioner

ZMDI's ZSSC3026 Low Power 16-Bit Sensor Signal Conditioner (SSC) is designed for high-accuracy amplification and analog-to-digital conversion of a differential input signal. Designed for high resolution altimeter module applications, the ZSSC3026 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, it can also provide a corrected temperature output measured with an internal sensor.

ZMDI ZLED7020 High Current LED Driver

ZMDI's ZLED7020 High Current LED Driver is a continuous-mode inductive step-down converter that is a part of the ZLED7x20 family of LED-control ICs. It is designed for applications requiring high brightness and high current. The ZLED7020 can efficiently drive a single LED or multiple series-connected LEDs from a voltage input higher than the LED forward voltage: Vin = 6 to 40 VDC. It provides an adjustable output current ≤1.2A, which is set via an external resistor and controlled by the ZLED7020's integrated high-side output current-sensing circuit and high speed internal 40V power switch. An external control signal, which can be a DC voltage, PWM, or microcontroller-generated waveform, on the ADJ pin can also be used to linearly adjust a continuous output current or to control a gated output current.

ZMDI ZLED7001 Universal LED Driver

ZMDI's ZLED7001 Universal LED Driver is one of ZMDI's ZLED family of LED control ICs, and is a peak current-mode control LED driver IC that is optimal for buck LED driver applications. The ZLED7001 operates in constant off-time mode. Capable of operating efficiently with voltage sources ranging from 8 VDC to 450 VDC or rectified 110 VAC/ 220 VAC, it is ideal for High Brightness (HB) LED applications. The ZLED7001 provides a PWM input for an external dimming control signal. The ZLED7001's linear dimming input can be used both for linear dimming (0 to 240 mV) and temperature compensation of the LED current. Because the ZLED7001's response time is limited only by the rate of change in the inductor current, it attains a high performance pulse-width modulation (PWM) dimming response. The ZLED7001 ensures proper output current regulation, without loop compensation, via peak current-mode operation.
