TPS62824ADMQR +BOM

2.4-V to 5.5-V input, 1-A step-down converter with forced PWM in 1.5-mm×1.5-mm QFN package

TPS62824ADMQR General Description

This versatile device is available in two variations. The first features an automatic power save mode for increased efficiency at light loads, extending system battery run-time. The second runs in forced-PWM, maintaining continuous conduction mode to minimize output voltage ripple and ensure a quasi-fixed switching frequency. Additionally, the TPS62824ADMQR includes a Power-Good signal and internal soft-start circuit, and is capable of operating in 100% mode. For fault protection, the device incorporates HICCUP short-circuit protection and thermal shutdown. Housed in a 6-pin 1.5-mm × 1.5-mm QFN package, the TPS62824ADMQR offers a compact, high power density solution
