Description for the TPSM82810

TPSM8281x is a family of pin-to-pin 3-A and 4-A high efficiency and easy to usesynchronous step-down DC/DC converters. They are based on a peak current mode control topology.They are designed for Telecommunication, Test and Measurement and Medical applications with highpower density and ease of use requirements. Low resistive switches allow up to 4-A continuousoutput current at high ambient temperature. The switching frequency is externally adjustable from1.8 MHz to 4 MHz and can also be synchronized to an external clock in the same frequency range. InPWM/PFM mode, TPSM8281x automatically enters Power Save Mode at light loads to maintain highefficiency across the whole load range. TPSM8281x provides a 1% output voltage accuracy in PWM modewhich helps design a power supply with high output voltage accuracy. The SS/TR pin allows settingthe start-up time or forming tracking of the output voltage to an external source. This allowsexternal sequencing of different supply rails and limiting the inrush current duringstart-up.

The TPSM8281x is available as an adjustable version, packaged in a 3-mm x 4-mm µSilmodule with integrated inductor.
