OUTLINE
Each of the RV5VH series is dual output CMOS DC/DC converter ICs integrating Step-up and inverting DC/DC converters. The RV5VH3××series ICs consists of an oscillator, two VFM control circuits, control transistors(EXT switches), a phase shift circuit, a voltage reference unit, an error amplifier, and voltage sensing resistors. The package for the RV5VH series is 8pin SSOP(0.65mm pitch), and it is suitable for power supply systems with positive and negative output, such as pager, PDA, which need power supplies for LCD.
