Description

10A, 18V, 500kHz, ACOT™ Synchronous Step-Down ConverterThe RT2810B is a synchronous step-down converter with Advanced Constant On-Time (ACOT™) mode control.The ACOT™ provides a very fast transient response with few external components. The low impedance internalMOSFET supports high efficiency operation with wide input voltage range from 4.5V to 18V. The proprietary circuitof the RT2810B enables to support all ceramic capacitors. The output voltage can be adjustable between 0.7V and8V. The soft-start time is adjustable by an external capacitor.
