TPSM82810에 대한 설명
TPSM8281x is a family of pin-to-pin, 3A and 4A compatible, high-efficiency, and easy to use synchronous step-down DC/DC power modules with integrated inductors. The devices are based on a fixed-frequency peak current-mode control topology and they support high power density requirements for telecommunication, test and measurement, and medical applications. Low resistance switches allow up to 4A continuous output current at high ambient temperatures. The switching frequency is externally adjustable from 1.8MHz to 4MHz and can also be synchronized to an external clock in the same frequency range. In PFM/PWM mode, the TPSM8281x maintains high efficiency across the whole load range. The TPSM8281x provide 1% output voltage accuracy in PWM mode, which enables designing power supplies with high output voltage accuracy. The SS/TR pin helps limiting inrush current through a precise start-up ramp. It also supports sequencing by tracking the output voltage to an external source. The family is available in a 14-pin µSIL package with nominal 3.0mm × 4.0mm footprint and in a 13-pin MagPack package with nominal 2.5mm × 3.0mm footprint.
