G5916 Overview
The G5916 is a charge pump for high-current white LED driving used in camera flash applications. The architecture of two bucket capacitors is used to decrease the output ripple and provides low EMI solution pared to inductive DC-DC regulators. The G5916 has independent flash/torch/shutdown modes.
G5916 Key Features
- Independent flash/torch/shutdown modes

- Torch mode set to 20% of flash current
- 1X/2X mode for torch mode to maximize effi
- Wide input voltage range from 3V to 5.5V
- <1μA shutdown current
- Input/Output over-voltage protection
- Short-circuit protection
- Over-temperature protection
