HI-SINCERITY Spec. No. : IC200915 Issued Date : 2009.08.12 Revised Date : Page No. : 1/8 MICROELECTRONICS CORP. 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. Features Applications · Constant Voltage and Constant Current Control · Adapters · Precision Internal Voltage Reference · Battery Chargers · Few External Components · Easy Compensation · Low Supply Current · Operating Temperature Range: -40 to 105℃ Pin Configuration H234 Pin Number Pin Name Function 1 VCTRL Input pin of the voltage control loop 2 GND Ground 3 VOUT Output pin.
