一、General Description
SY7200A is DC/DC step-up converter that deliver an accurate constant current for driving LEDs. Operation at a fixed switching frequency of 1MHz allows thedevice to be used with small value external ceramic capacitors and inductor. LEDs connected in series are driven with a regulated current set by the externalresistor. The SY7200A is ideal for driving up to eight white LEDs in series or up to 30V.
二、Features
1. Input voltage range: 2.8 to 30V
2.Switch current limit 2A
3.Drives LED strings up to 30V
4.1MHz fixed frequency minimizes the external components
5.Dimming frequency for EN/PWM pin: 20kHz~1MHz
6.Internal softstart limits the inrush current
7.Open LED over voltage protection
8.RoHS Compliant and Halogen Free
三、Applications
1. GPS Navigation Systems
2.Handheld Devices
3. Portable Media Players
