1 Introduction

The TPS7H4104 and TPS7H4102 are 7V, 3A per channel, multichannel, peak-current mode, synchronous buck converters optimized for use in area sensitive, space environment applications. The device incorporates four (TPS7H4104) or two (TPS7H4102) identical channels that can be use to step down the power input voltage into independent voltages up to 3A per phase or interleaved to increment the output current up to 12A (TPS7H4104) or 6A (TPS7H4102).

Each channel incorporates:

• High and low side power MOSFETs with programmable soft-start and slope compensation
• Power-good flags and enable signaling

The device also offers:

• An EN_SEQ input to create a sequential power up and reverse sequence power down
• Current limit mechanisms for robust current limiting during fault conditions
• Thermal shutdown to disable the device if the die temperature exceeds the thermal limit

The device is offered in a 64-pin plastic package. General device information and test conditions are listed in the overview information table. For more detailed technical specifications, user-guides, and application notes please go to device product page.
