RT2810A/B
10A, 18V, 500kHz, ACOT^TM Synchronous Step-Down Converter
General Description
Features
The RT2810A/B is a synchronous step-down converter
with Advanced Constant On-Time (ACOT^TM) mode control.
The ACOT^TM provides a very fast transient response with
few external components. The low impedance internal
MOSFET supports high efficiency operation with wide
input voltage range from 4.5V to 18V. The proprietary circuit
of the RT2810A/B enables to support all ceramic
capacitors. The output voltage can be adjustable between
0.7V and 8V. The soft-start is adjustable by an external
capacitor.
