DC/DC CONVERTER

CONTROLLER

RV5VH SERIES

APPLICATION MANUAL

NO. EA-049-0006

DC/DC CONVERTER CONTROLLER

RV5VH SERIES

OUTLINE

Each of the RV5VH series is dual output CMOS DC/DC converter ICs integrating Step-up and inverting DC/DC convert-

ers.

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.

RV5VH1

××

and RV5VH2

××

series are able to provide two DC/DC converters, one is a step-up DC/DC converter with

internally fixed output and the other is an inverting DC/DC converter with adjustable output by external resistors. A volt-

age detector with sensing pin is also included. RV5VH3

××

series are able to provide two DC/DC converters, both of them

require external drivers, DC/DC1, and inverting one, DC/DC2, can be adjustable by resistors.

FEATURES

• Dual DC/DC converter system .................................DC/DC1 : step-up

DC/DC2 : inverting(negative voltage)

• Voltage Detector ..........................................................Nch. Open Drain Output

• Low voltage operation available
