CS5361
Battery Charger
Buck Controller
The CS5361 is a high voltage step down controller that provides a
simple way to build a battery charger suited for various types of
batteries. With an operating range of up to 30 V, it can be used to
charge a multiple number of cells from a DC voltage, as is supplied by
high AC–DC adapter voltages. Proprietary I

architecture ensures full
control over both Average and Peak charging currents. Independent
voltage loop allows for precision regulation of the battery voltage.
Average current outer control loop provides tight regulation and easy
loop compensation while pulse by pulse inner control provides for fast
response.
The CS5361 is designed to provide a high performance,
full–featured battery charger that is simple to use. A 4.2 V reference
with 0.8% tolerance can be used to implement 1.0% accurate output
voltages. It also features an additional pulse–by–pulse current limit
input to allow for fast output current control.
The CS5361 operates over a 7.0 V to 30 V range and is available in a
16 lead surface mount narrow body.
