Step-Up DC/DC Controller



General Description

The OCP3601 is a boost topology switching regulator control IC for battery-used applications field. The OCP3601

includes a totem-pole single output stage for driving NPN transistor or N-MOS, high precision reference (0.5V) for

comparing output voltage with feedback amplifier, an internal dead-time control for controlling the minimum duty cycle,

programmable soft start with short circuit protection function and logic level control for operating mode or standby

mode.
