RT2855B, RT2855A Synchronous Step-Down Converter

RT2855B Description

® RT2855A/B 4A, 18V, 650kHz, ACOT® Synchronous Step-Down Converter General .
The RT2855A/B are high-performance 650kHz 4A stepdown regulators with internal power switches and synchronous rectifiers.

RT2855B Features

* a power-saving discontinuous operating mode at light loads. Features
* Fast Transient Response
* Steady 650kHz Switching Frequency at all Load Current (RT2855B)
* Discontinuous operating mode at Light Load (RT2855A)
* 4A Output Current
* Advanced Constant On-Time (ACOT®) Control

RT2855B Applications

* especially for low output voltages and low duty cycles. Cycle-bycycle current limit, input under-voltage lock-out, externallyadjustable soft-start, output under- and over-voltage protection, and thermal shutdown provide safe and smooth operation in all operating conditions. The RT2855A and RT2855B
