FAN7310

Full-Bridge Backlight Inverter/Driver IC

Full-bridge inverter/driver IC integrates a pulse width modulation (PWM) controller in a 20 Lead SSOP package. This compact part offers an efficient, low part count solution for portable LCD backlighting applications. The FAN7310 supports analog, mixed, and burst - dimming modes of operation; has a wide input range (5V-24V); and offers a variety of circuit protection features for further reliability. In addition to advanced phase shift control for improved thermal characteristics, the FAN7310 also offers alternate zero voltage switching (ZVS) and zero current switching (ZCS) full-bridge topology, while consuming less than 4mA (typical) operating current.

Features and Benefits

   - Open lamp regulation (OLR)
   - Open lamp protection (OLP)
- Internal shunt regulator allows operation across a wide input voltage range
- 4mA operating current improves overall system efficiency

Applications

- Notebook PCs
- LCD monitors
- Auto navigation systems
