SY7301A Description
SY7301A 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. LEDs connected in series are driven with a regulated current set by the external resistor.
SY7301A Key Features
- Input voltage range: 2.8 to 40V
- Switch current limit:2A
- Drives LED strings up to 40V
- 1MHz fixed frequency minimizes the external
- 200Hz~1MHz dimming frequency for EN/PWM
- Internal softstart limits the inrush current
- Open LED over voltage protection
- RoHS pliant and Halogen F ee
- pact package: TSOT23 -6/DFN3X3-10
SY7301A Applications
- Input voltage range: 2.8 to 40V
