TPS54428DDAR General Description
The TPS54428 is an adaptive on-time D-CAP2™ mode synchronous buck converter.
The TPS54428 enables system designers to complete the suite of various end-equipment power bus regulators with a cost effective, low component count, low standby current solution.
The main control loop for the TPS54428 uses the D-CAP2™ mode control that provides a fast transient response with no external compensation components.
The adaptive on-time control supports seamless transition between PWM mode at higher load conditions and Eco-mode™ operation at light loads.
Eco-mode™ allows the TPS54428 to maintain high efficiency during lighter load conditions.
The TPS54428 also has a proprietary circuit that enables the device 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.
The output voltage can be programmed between 0.76 V and 7.0 V.
The device also features an adjustable soft start time.
The TPS54428 is available in 8-pin DDA package and 10-pin DRC packages, and is designed to operate over the ambient temperature range of –40°C to 85°C.
