Product overview
概要
This evaluation board is dedicated to the design of a flash LED driver using the STCF02 step-up/ down current mode converter, providing the proper recommendations for PCB layout and external components. The device can operate in five modes which are selected using a combination of logic signals (connected to three enable pins). Also implemented is a simple programmable RC circuit used to shut down the device to prevent LED burning during flash mode in the event of microcontroller fault. This evaluation board drives a single flash LED with a forward voltage range of 2.7 to 5 V.

All features
- Flash LED driver based on the STCF02 highpower white LED driver
- The device can operate in five modes which are selected using a combination of logic signals (connected to three enable pins) Five selectable operating modes:
Shutdown mode: quiescent current less than 1μA (typical) Shutdown mode with activated negative temperature coefficient (NTC) LED temperature sensing, useful for measuring the temperature before starting both torch and flash modes Torch mode: drives the LED up to 250 mA Flash mode: drives the LED up to 600 mA Middle flash mode: the current is set between the torch and the flash mode levels - A High operating frequency: 1.8 MHz
