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
6-Lead Plastic SOT-23-6LTSOP-6
Package Code: N
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.
Features
· Constant Voltage and Constant Current Control
· Precision Internal Voltage Reference
· Few External Components
· Easy Compensation
· Low Supply Current
· Operating Temperature Range: -40 to 105
Applications
· Adapters
· Battery Chargers
