STCF02 is a high efficiency single LED driver for mobile phones and digital still cameras. It supports multiple working modes, and provides LED temperature protection, output current control, short circuit protection and other functions
The STCF02 is a high efficiency power supply solution designed to drive a single flash LED in cell phones, PDAs, and other hand-held devices. It operates as a buck-boost converter, ensuring proper LED current control over the battery voltage range of 2.7V to 4.5V. The device features adjustable output current and supports multiple operational modes including Shutdown, Torch, Flash, and Medium Flash, selectable via three logic input signals.
| Input Operating Voltage | 2.7 to 5.5 V |
|---|---|
| Output Current (Flash mode) | Up to 600 mA |
| Output Current (Torch mode) | Up to 250 mA |
| Operating Frequency | 1.8 MHz (typ) |
| Package Type | QFN20 (4mm x 4mm) |
The input operating voltage ranges from 2.7V to 5.5V.
The device supports five modes: Shutdown, Shutdown with NTC, Torch, Medium Flash, and Flash.
The device limits the peak inductor current to 2.3A (typical).
