DESCRIPTION
Current mode and fixed frequency operation provides fast transient response and eases loop stabilization. With a current sense amplifier threshold of 205mV, the LED current is programmable with one external current sense resistor and the power loss is minimized. The 450kHz operating frequency minimizes external inductor, input and output capacitor. The MT7285 supports both PWM and analog dimming by a single control pin. Fault condition protection includes over voltage protection (OVP), cycle-by-cycle peak current limiting and thermal shutdown. The MT7285 is available in ESOP8 packages. FEATURES
