LMZ1 SIMPLE SWITCHER power modules are ideal for applications requiring a standard feature set. All power modules in the LMZ1 series have a precision enable pin and soft-start pin. LMZ1420x Power Modules are easy-to-use, step-down DC-DC solutions with exceptional power conversion efficiency, line and load regulation, and output accuracy.

High Output Voltage Power Modules: LMZ1420xH SIMPLE SWITCHER power modules have an output voltage range from 5V to 30V. These power modules are ideal for intermediate rail conversions, powering fans or other types of non-traditional points of load, and for sensing applications requiring voltages below -6V. Extended Temperature (EXT) Power Modules: SIMPLE SWITCHER EXT power modules provide excellent performance in the most extreme conditions, with extended ambient temperatures guaranteed down to -55ºC.

LMZ2 SIMPLE SWITCHER power modules are available in output currents up to 10A with additional features for powering high current intermediate rails, FPGAs, and noise sensitive applications. They also feature a frequency synchronization pin that controls the switching frequency of the internal circuitry, and a current sharing pin for paralleling multiple power modules together for achieving up to 60A of output current.

Texas Instruments SIMPLE SWITCHER® Controllers are easy to use and simplified step down power controllers capable of providing up to 12A of output current in a typical application. TI LM3151 / LM3152 / LM3153 SIMPLE SWITCHER Controllers operate with an input voltage range from 6V-42V, feature a fixed output voltage of 3.3V and offer switching frequencies of 250kHz, 500kHz, and 750kHz. LM3150 offers adjustable output to 1MHz. These SIMPLE SWITCHER Controllers employ a Constant On-Time (COT) architecture with a proprietary Emulated Ripple Mode (ERM) control that allows for the use of low ESR output capacitors, which reduces overall solution size and output voltage ripple. These synchronous step-down controllers are designed for use in telecom, networking equipment, security surveillance, and other applications.
