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 the high-side and low-side power MOSFETs with programmable soft-start and slope compensation. Additionally, per channel power-good flags and enable signals are provided. The TPS7H4104 also includes an EN_SEQ input that enables a sequential power‑up and a reverse‑sequence power‑down.
Various current limit mechanisms are included for robust current limiting during fault conditions. Thermal shutdown disables the device when the die temperature exceeds thermal limit.
