HT3494 is a wide input voltage, high efficiency CCstep-down DC/DC converter that operates in either CV
(Constant Output Voltage) mode or CC (Constant Output Current) mode. HT3494 provides up to 5A output current
at 200kHz switching frequency.
Protection features include cycle-by-cycle current limit, thermal shutdown, and integrated soft start. The devices
are available in a SOP-8EP package and require very few external devices for operation.
