1.5A,Step-Up/Down/Inverting Switching Regulators

The CP34063 Series is a monolithic control circuit containing the

primary functions required for DC–to–DC converters. These devices

consist of an internal temperature compensated reference, comparator,

controlled duty cycle oscillator with an active current limit circuit,

PDIP–8

driver and high current output switch. This series was specifically

designed to be incorporated in Step–Down and Step–Up and

Voltage–Inverting applications with a minimum number of external

components.

SOP–8

• Operation from 3.0 V to 40 V Input

• Low Standby Current

• Current Limiting

• Output Switch Current to 1.5 A

• Output Voltage Adjustable

PIN CONNECTIONS

• Frequency Operation to 100 kHz

• Precision 2% Reference
