TECHNICAL NOTE

Regulator IC Series for Digital Still Cameras / Digital Video Cameras

Strobe Charge Control ICs

BD4211FV / BD4210EKN

zDescription

The strobe charge control IC is a self-oscillating switching regulator that uses a transformer. Its provides highly efficient

charge capacitors in strobe applications.

zFeatures

1. Adjustable transformer primary-side peak current (BD4210EKN)

2. The third stages switching transformer primary-side peak current (BD4211FV)

3. Built-in power transistor

4. The power transistor off time can be controlled with the RT pin, allowing the charge time to be set externally.

5. Standby mode switching with the START pin

6. Includes charge complete signal output (FULL) pin.

7. Includes charge voltage detection (VC) pin (can be set externally).

8. Built-in thermal shutdown circuit (TSD)

9. Built-in IGBT driver (BD4210EKN)

zApplications

Digital still cameras, single-lens reflex cameras, digital video cameras
