HT7936B Overview
Description
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 capacitor, to implement a full step-up conversion function.
Key Features
- Input voltage range: 2.8V to VOUT
- Driving current: 110mA (HT7936A)
- Oscillator frequency: 1MHz
- Soft start function, current limit, 150mA (HT7936B)
- Fixed output voltage: 5V (HT7936A), short circuit protection
