The TPS56428RHLT is a D-CAP2 mode synchronous buck converter which is optimized for various power bus regulation needs with a cost effective, low component count, low standby current solution.
The D-CAP2 mode control provides a fast transient response with no external compensation components. This adaptive on-time control supports seamless transition between PWM mode at higher load conditions and advanced Eco-mode operation at light loads. Advanced Eco-mode™ maintains higher efficiency during lighter load conditions than traditional skip mode.
The TPS56428RHLT also has a proprietary circuit to adopt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The device operates from 4.5-V to 18 V VIN input and its output voltage can be programmed between 0.6V and 7.0V. The device also features a fixed 1-ms soft start and a power-good output.
