SY7203
Overview
SY7203 develops a step-up DC/DC converter that delivers an accurate constant current for driving LEDs. Operating at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor.
- Input voltage range: 2.8 to 30V
- Switch current limit: 4A
- Drives LED strings up to 30V
- 1MHz fixed frequency minimizes the external components
- 20kHz~1MHz wide dimming frequency range for EN/PWM pin
- Internal softstart limits the inrush current
- Open LED over voltage protection
- RoHS Compliant and Halogen Free
- Compact package: DFN3X3-10
