General Description<\/h3>\n\n\n\n

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.<\/p>\n\n\n\n

EC9302 provides up to 2.5A output current at 160kHz switching frequency.<\/p>\n\n\n\n

Current mode control provides fast transient response and cycle-by-cycle current limit.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n
