RT9287

Pinout




Description

The RT9287 integrates a boost converter for OLED power and a Dual LDO for camera image sensor power. To achieve high efficiency, the boost converter optimizes its operating frequency for small LC filters value and reduces the operating current. Moreover, the internal soft-start function reduces the inrush current.
For the Dual LDO part, it possesses functions of 2% accuracy, dual channel, low dropout voltage (240mV@300mA), low noise, low ground current and low dropout regulator sourcing up to 300mA at each channel. For battery-powered devices, it provides near zero shutdown current. Moreover, it also integrates functions such as current limiting, over temperature, output short circuit, 27uA low ground current per LDO and short circuit thermal folded back protection. When output short circuit occurs, the RT9287 reduces its over temperature protection trip point to provide maximum safety to users. The RT9287 is available in WDFN-10L 3x3 package.
