10A, 18V, 500kHz, ACOT^TM Synchronous Step-Down Converter

RT2810A/RT2810B

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.

Applications
