Built-in OVP White LED Step-up Converter

The HT7937 is high efficiency boost converter with a constant current output to provide back light functions in handheld devices. Applications with series connected LEDs ensure constant and identical LED currents re- sulting in uniform brightness. A continuous LED output current is setup using the F Integrated open-circuit protection\nOver voltage protection\nUp to 84% efficiency at VIN=3V, 3LEDs, ILED= 20mA\n1.2MHz fixed switching frequency\nLow standby current: 0.1µA (typ.) (VSHDN=0V)\nMatches LED current\nSmall value inductor and capacitors\nSmall outline SOT23-6 package;
