The TPS54429E is an adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54429E enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54429E uses the D-CAP2™ mode control which provides a very 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 TPS54429E to maintain high efficiency during lighter load conditions. The TPS54429E also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP, SP-CAP, and ultra-low ESR ceramic capacitors. The device operates from 7-V to 18-V VIN input. The output voltage can be programmed between 0.76V and 5.5V. The device also features an adjustable soft start time and a power good function. The TPS54429E is available in the 14-pin HTSSOP package and the 16 pin QFN package, designed to operate from –20°C to 85°C.
