3 Channel DC-DC Converters IC with High-Efficiency StepUp and Step-Down
General Description
The RT9907 is a three channel power-supply solution for digital still cameras and other battery-powered devices. It integrates an asynchronous step-up and two synchronous step-down DC-DC converters. The RT9907 is targeted for applications that use two AA cells or a single lithium-ion battery.
The three DC-DC converters (CH1, CH2, CH3) accept input voltage from 1.5V to 5.5V. Each DC-DC converter has better transient response and excellent stability by providing current-mode control and external pensation network. With built-in Internal MOSFET and up to 1.4MHz operating frequency, the...
