FAN5607 is a high-efficiency LED driver from Fairchild Semiconductor. The driver adopts three operating modes, with an output current of up to 120mA and a support voltage range of 2.4V-5.5V. The driver also has an internal switching reconfiguration and fractional switching technology to achieve high efficiency across the entire input voltage range. In addition, the driver has internally matched LED current sources, adaptive VOUT adjustment, soft-start, short circuit protection and other features.
The FAN5607 is a parallel LED driver with an internally matched current source and an adaptive charge pump that supports three modes of operation: 1X, 1.5X, and 2X. It generates regulated output current from a battery with input voltages varying between 2.4V and 5.5V.
| Input Voltage Range | 2.4V to 5.5V |
|---|---|
| Maximum Output Current | Up to 120mA (4 x 30mA) |
| Package Type | 4x4mm 16-lead MLP |
| Peak Efficiency | Up to 93% |
The built-in charge pump has three modes of operation: 1X, 1.5X, and 2X Mode.
The maximum LED current can be programmed using an external resistor.
