SY7203 Description
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. The LED current is programmable through the external resistor.
SY7203 Key Features
- Input voltage range: 2.8 to 30V
- Switch current limit: 4A
- Drives LED strings up to 30V
- 1MHz fixed frequency minimizes the external
- Internal softstart limits the inrush current
- Open LED over voltage protection
- RoHS pliant and Halogen Free
- pact package: DFN3X3-10
SY7203 Applications
- Input voltage range: 2.8 to 30V
