GENERAL DESCRIPTION
CEP8113A is a wide input voltage, high efficiency CC
step-down DC/DC converter that operates in either CV
(Constant Output Voltage) mode or CC (Constant
Output Current) mode. CEP8113A provides up to 3.5A
output current at 125kHz switching frequency.
CEP8113A provides OVP pin for output over voltage
protection.
Protection features include cycle-by-cycle current limit,
thermal shutdown, and frequency foldback at short
circuit. The devices are available in a SOP-8EP
package and require very few external devices for
operation.
