SP7601
Overview
- 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
- 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. TYPICAL APPLICATION CIRCUIT M1 L1 VIN Cin 1 Vin Vo / LED + up to 29V 2 Gate 6 LX D1 Rs LED1 GND C1 0.1uF 3 SP7601 LEDn
