38V Synchronous Buck Converter With CC/CV ^EC9302
General Description
Features
EC9302 is a wide input voltage, high efficiency Active
CC step-down DC/DC converter that operates in either
CV (Constant Output Voltage) mode or CC (Constant
Output Current) mode.EC9302 provides up to 2.5A
output current at 160kHz switching frequency. Current
mode control provides fast transient response and
cycle-by-cycle current limit.
An internal soft-start prevents inrush current at turn-on,
This device, available in an SOP8L-EP(Exposed pad)
package, provides a very compact solution with minimal
external components.
