SP435W

Dual OP AMP with Voltage Regulator

DESCRIPTION

APPLICATIONS

The SP435W is a monolithic IC specifically designed to

control the output current and voltage levels of switch

mode battery chargers and power supplies.

Battery Power Equipment

Linear Regulators

Switch Power Supply

Cellular Phone

Digital Cameras

Computer Disk Drivers

The device contains two operational amplifiers and a

precision shunt regulator. Op Amp 1 is designed for

voltage control, whose non-inverting input internally

connects to the output of the shunt regulator. Op Amp 2

is for current control with both inputs uncommitted. The

IC offers the power converter designer a control

solution that features increased precision with a

corresponding reduction in system complexity and cost.
