The TPSM560R6H converter is an easy-to-use, synchronous buck, DC-DC power module that operates from a 4.2-V to 60-V supply voltage. The device is intended for step-down conversions from 5-V, 12-V, 24-V, and 48-V unregulated, semi-regulated, or fully-regulated supply rails. With an integrated power controller, inductor, and MOSFETs, the TPSM560R6H delivers up to 600-mA DC load current, with high efficiency and ultra-low input quiescent current, in a very small solution size. Although designed for simple implementation, this device offers flexibility to optimize its usage according to the target application. Control-loop compensation is not required, reducing design time and external component count.

The TPSM560R6H incorporates several features for comprehensive system requirements, including the following:

• Open-drain power-good circuit for power-rail sequencing and fault reporting
• Monotonic start-up into prebiased loads
• Precision enable with customizable hysteresis for programmable line undervoltage lockout (UVLO)
• Overcurrent and thermal shutdown with automatic recovery
