PRODUCT NAME

ICF CP2101

FUNCTIONAL DESCRIPTION

Switcher Power Converter

APPLICATIONS

Simple high-efficiency step-down (buck) regulator

On-card switching regulators

Positive to negative converter

GENERAL DESCRIPTION

The ICF CP2101 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 5.1V and an adjustable output version.

Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator. The ICF CP2101 series operates at a switching frequency of 165 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.

Other features include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring typically 100 µA standby current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions.
