SY7201 Description
SY7201 and SY7201A are DC/DC step-up converters that deliver an accurate constant current for driving LEDs. Operation at a fixed switching frequency of 1MHz allows the device to be used with small value external ceramic capacitors and inductor. LEDs connected in series are driven with a regulated current set by the external resistor.
SY7201 Key Features
- Input voltage range: 2.8 to 30V
- Switch current limit 2A
- Drives LED strings up to 30V
- 1MHz fixed frequency minimizes the external
- Dimming frequency for EN/PWM pin
- Internal softstart limits the inrush current
- Open LED over voltage protection
- RoHS pliant and Halogen Free
- pact package: SOT23-6 pin
