SL71051
CC, CV Control for Battery Charger & Adaptor
Description
SL71051 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC
(constant current) mode. SL71051 integrates one voltage reference, two operational amplifiers (with
ORed outputs-common collectors), and a current sensing circuit. The voltage reference combined with
one operational amplifier makes it an ideal voltage controller, and the other low voltage reference com-
bined with the other operational amplifier makes it an ideal current limiter for output low side current
sensing. the current threshold is fixed, and precise. the only external components are :
-. a resistor bridge to be connected to the output of the power supply (adapter, battery charger) to set the
voltage regulation by dividing the desired output voltage to match the internal voltage reference value.
-. a sense resistor having a value and allowable dissipation power which need to be chosen according to
the internal voltage threshold.
-. optional compensation components (R and C). SL71051, housed in one of the smallest package
available, is ideal for space shrink applications such as adapters and battery chargers.
