SP7601

29V High Voltage LED Driver

FEATURES

Wide Input Voltage Range 4.5V 鈥?29V

1.2MHz Constant Frequency Operation

Low 0.2V Reference Voltage

Adjustable Overcurrent Protection

PWM Dimming and Power sequencing Control

RoHS Compliant, Lead Free Packaging:

Small 6-Pin TSOT Package

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.
