Texas Instruments TPSM82816 DC/DC Power Module

Texas Instruments TPSM82816 DC/DC Power Module is based on a fixed-frequency peak current-mode control topology. This power module is pin-to-pin 3A, 4A, and 6A compatible high, efficiency and easy to use synchronous step-down DC/DC power modules with integrated inductors. The TPSM82816 module operates at an adjustable frequency range from 1.8MHz to 4MHz and can be synchronized to an external clock in the same frequency range. This DC/DC module provides a 1% output voltage accuracy in PWM mode that helps design a power supply with high output voltage accuracy. The TPSM82816 module is used in optical modules, data center interconnect, signal measurement, source generation, instrumentation, patient monitoring and diagnostics, wireless infrastructure, and ruggedized communication.
