SP7601
29V High Voltage LED Driver
FEATURES
Wide Input Voltage Range 4.5V – 29V
1.2MHz Constant Frequency Operation
Low 0.2V Reference Voltage
Adjustable Overcurrent Protection
PWM Dimming and Power sequencing Control

DESCRIPTION
The SP7601 is a high current DC to DC Switching Buck LED Driver that features low component
count and high efficiency due to a very low 0.2V reference voltage. High 1.2MHz switching
frequency allows use of very small external components. The SP7601 is compatible with PWM
dimming up to a frequency of 1kHz at 10% Duty Cycle.
