HM3800S
BOOST CONVERT CONTROL IC
GENERAL DESCRIPTION
The HM3800 is a boost topology switching
regulator control IC for battery-used applications field.
The HM3800 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.
