H234

Description

6-Lead Plastic SOT-23-6L（TSOP-6）

Package Code: N

The H234 is a highly integrated solution for a constant voltage/constant

current mode SMPS application.

The H234 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 H234 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 H234 is available in SOT-23-6L( TSOP-6 ) package.
