This image/catalog/ LED driver can be used directly to drive LEDs without  requirement for extra converters. All components required are soldered on a minimized PCB, providing a cost-effective solution. Two location mounting holes make the installation easier.
This driver integrates an MBI6651chip (TO252 packaging) as the step-down DC-DC converter.  It is a high efficient chip which is designed to deliver constant current to power high intensity image/catalog/ STAR LEDs. Features of MBI6651 help make its applications safer, such as UVLO (under voltage lock out), over temperature protection, LED open-circuited protection and LED short-circuited protection. Moreover, thermal protection (TP) function has been introduced to protect IC from overheating (165°C).
  • Size: 45.80(L) × 25.50(W) × 17.80(H)  ±0.2mm            
  • Input voltage: 9V to 35V            
  • 82% efficiency @ input voltage 24V, 2 LEDs            
  • Typical 1000mA output current            
  • PWM frequency: 100HZ to 1KHZ            
  • Step-down DC/DC            
  • Constant current output            
  • TO252 packaging of MBI6651 helps heat dissipation            
  • Allows users to control the dimming via an external PWM            
  • Easy installation and long service life
