General Description
The SP1236FH is a synchronous buck Regulator with
output current to 3.1A. It is designed to allow for operating
a wide supply voltage range from 8V to 40V. The internal
compensation requires a minimum number of readily
available standard external components.
The SP1236FH operates in the CC(Constant output
Current) mode or CV(Constant output Voltage) mode, and
the OCP current value is set by current sensing power
resisters or setting non power resisters.
The SP1236FH is suitable for the DC/DC switching power
applications when requested the current limit function.
The devices are available in SOP-8L package and require
very few external devices for operation.
Applications
Car Chargers
Portable Charger Devices
DC/DC Converters with Current Limit
