HT7936A Datasheet (Holtek Semiconductor) - White LED Step-up Charge Pump Converter

HT7936A, White LED Step-up Charge Pump Converter

The HT7936A and HT7936B are charge-pump type DC-DC step-up converter devices, which can generate regulated fixed output voltages of 5.0V and 4.5V.

Their high degree of functional integration requires only the addition of three external capacitors, namely a flying capacitor and an input and output ca
