The NCP5810D is a dual-output DC/DC converter that generates both a positive and a negative voltage. Its boost output is internally fixed at +4.6 V, while the negative buck-boost inverter output is configurable with external feedback resistors from -2.0 V to -15.0 V. The PWM converters switch at 1.75 MHz and are internally compensated in a 12-pin 3 x 3 x 0.55 mm UDFN package.
The datasheet presents features, a typical application circuit, a simplified block diagram, pin function descriptions, maximum ratings and electrical characteristics. Typical applications listed are AMOLED driver supply, cellular phones, digital cameras, personal digital assistants, portable media players and GPS.
