Introduction

AI Translation

TPS54228 is an adaptive on-time D-CAP2™ mode synchronous buck converter. It helps system designers complete power bus regulator sets for various end equipment with a low-cost, low-component-count, low standby current solution. The main control loop uses D-CAP2™ mode control, achieving fast transient response without external compensation components. Adaptive on-time control enables seamless transition between PWM mode at higher load conditions and Eco-mode™ operation at light loads. Eco-mode™ allows the TPS54528 to maintain high efficiency under light load conditions. In addition, proprietary circuitry helps enable the device to support low equivalent series resistance (ESR) output capacitors such as POSCAP or SP-CAP, as well as ultra-low ESR ceramic capacitors. The device operates with an input voltage range of 4.5 V to 18 V. The output voltage is programmable between 0.76 V and 6 V. The device also features an adjustable soft-start time. Available in an 8-pin DDA package, designed for an operating temperature range of -40°C to 85°C.
