TYPICAL PERFORMANCE CHARACTERISTICS
Unless otherwise specified, the following conditions apply: VIN = 48V, CIN is a 2.2µF 100V X7R ceramic capacitor for driving
5–13 power LEDs with ILED = 350mA. Single LED forward voltage used is 3.2V. TA = 25°C for efficiency curves and
waveforms.
Efficiency vs VIN, ILED = 350mA
ILED Regulation vs VIN, ILED = 350mA
