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 • Input voltage range: 2.8V to VOUT\n• Driving current: 110mA (HT7936A), 150mA (HT7936B)\n• Fixed output voltage: 5V (HT7936A), 4.5V (HT7936B)\n• Oscillator frequency: 1MHz\n• Soft start function, current limit, short circuit protection\n• Small outline 6-pin SOT23 package;
