RT2810B
RT2810B is Synchronous Step-Down Converter manufactured by Richtek.
- Part of the RT2810A comparator family.
- Part of the RT2810A comparator family.
Description
Features
The RT2810A/B is a synchronous step-down converter with Advanced Constant On-Time (ACOTTM) mode control. The ACOTTM provides a very fast transient response with few external ponents. 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.
