Update: 30 September, 2023

The R1286 series 2ch DC/DC power converter is designed for AMOLED display power source. It contains a step up DC/DC converter and an inverting DC/DC converter. Step up DC/DC converter generates boosted output voltage to 4.6V ~ 5.8V(Selectable). Inverting DC/DC converter generates negative voltage down to -2.0V ~ -6.0V(Selectable) that is dynamically adjustable with single wire interface signal. R1286 consist of a voltage reference, error amplifiers, an oscillator, PWM control circuits, over current protection circuits, short protection circuits, an under voltage lockout circuit (UVLO), thermal shutdown circuit, a NMOS driver and a synchronous PMOS switch for boost converter, a PMOS driver and a synchronous NMOS switch for inverting converter, and so on.
