Maxim Integrated is a world leader in both highly-integrated and discrete power management and battery charging solutions. Maxim power includes more than 1,800 products for all forms of portable power management, harsh automotive environments, and line-powered conversion.
Maxim Integrated MAX17505 high-efficiency, high-voltage, synchronously rectified step-down converter with dual integrated MOSFETs operates over a 4.5V to 60V input. It delivers up to 1.7A and 0.9V to 90%VIN output voltage. Built-in compensation across the output voltage range eliminates the need for external components. The device features a peak-current-mode control architecture with a MODE feature that can be used to operate the device in pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous-conduction mode (DCM) control schemes. The low-resistance, on-chip MOSFETs ensure high efficiency at full load and simplify the layout. A programmable soft-start feature allows users to reduce input inrush current. The device also incorporates an output enable/undervoltage lockout pin (EN/UVLO) that allows the user to turn on the part at the desired input-voltage level. An open-drain active-low RESET pin provides a delayed power-good signal to the system upon achieving successful regulation of the output voltage.
Maxim's MAX13256 H-Bridge Transformer Driver provides a simple solution for making isolated power supplies up to 10W. The device drives a transformer’s primary coil with up to 300mA of current from a wide 8V to 36V DC supply. The transformer’s secondary-to-primary winding ratio defines the output voltage, allowing selection of virtually any isolated output voltage. The device features adjustable current limiting, allowing indirect limiting of secondary-side load currents. The current limit of the MAX13256 is set by an external resistor. A FAULT output asserts when the device detects an overtemperature or overcurrent condition. In addition, the device features a low-power mode to reduce the overall supply current to 0.65mA (typ) when the driver is not in use. The device can be operated using the internal oscillator or driven by an external clock to synchronize multiple MAX13256 devices and precisely set the switching frequency. Internal circuitry guarantees a fixed 50% duty cycle to prevent DC current flow through the transformer, regardless of which clock source is used.
Maxim Integrated's MAX16067 and MAX16068 are 6-channel, flash-configurable system managers with nonvolatile fault registers that monitor and manage up to six system voltages simultaneously. The Maxim Integrated MAX16067 and MAX16068
flash-configurable system managers integrate an internal 1% accurate
10-bit analog to digital converter (ADC) that measures each input and
compares the result to one overvoltage and one undervoltage limit.
Device configuration information (including overvoltage and undervoltage
limits) and time delay settings are stored in nonvolatile flash memory.
These Maxim Integrated IC devices support a power-supply voltage of up to
14V and can be powered directly from the 12V intermediate bus in many
systems. The MAX16067 and MAX16068 are designed for use in
a variety of applications, including networking, equipment, telecom
equipment, storage/raid systems, and servers.
Maxim Integrated MAX15041 Step-Down DC/DC Regulator is a low-cost, synchronous DC-DC converter with an internal switch that delivers an output current up to 3A. Maxim Integrated's MAX 15041 Series Step-Down DC/DC Regulator
operates from an input voltage range of 4.5V to 28V and features a
peak-current-mode PWM controller with an internally fixed 350kHz
switching frequency and a 90% maximum duty cycle. This synchronous buck regulator
also features internal MOSFETs that provide better efficiency than
asynchronous solutions, thermal shutdown, overcurrent protection
(high-side sourcing and low-side sinking), an internal 5V LDO with
undervoltage lockout, and more. In addition, Maxim Integrated's MAX 15041 regulator ensures safe startup when powering into a prebiased output.
