General Description

The H134 is a highly integrated solution for a constant voltage/constant current mode SMPS application. The H134 contains one 1.21V voltage reference with ± 0.5% accuracy, one current sensing circuit and two operational amplifiers. Combining the voltage reference with one operational amplifier makes H134 an ideal voltage controller for use in adapters and battery chargers. The other low voltage reference combined with the other operational amplifier makes it an ideal current limiter for output low side current sensing.

The H134 is available in SOT-23-6L( TSOP-6 ) package.
