H60SB0A050NRDE Integrated Circuit Chip 50A 1/2 Brick DC/DC Regulated Power Module

The H60SB0A050 is a half-brick, non-isolated DC/DC regulated power supply module. It is a wide-input, high-current, adjustable POL (Point-of-Load) converter with standard half-brick dimensions of 63.2 × 60.6 × 13 mm. It features a single output channel with a maximum output current of 50 A, a peak power of up to 3,000 W, and a peak conversion efficiency of up to 98%.

The module supports the PMBus digital communication interface, enabling power telemetry, remote adjustment, fault monitoring, and configuration management. It natively supports current sharing and capacity expansion through parallel connection of multiple units, eliminating the need for additional external ORing anti-backflow MOSFETs and simplifying the design of high-power multi-module parallel systems. It also supports pre-biased start-up, making it suitable for power-up scenarios involving loads with residual voltage.
