BD9422EFV

Datasheet LED Drivers for LCD Backlights White LED Driver for large LCD panel BD9422EFV ●General Description BD9422EFV is a high efficiency driver for white LEDs and designed for large LCD panel. This IC is built-in high current drive and high responsibility type 6ch LED drivers and 1ch boost DCDC converter. BD9422EFV has some protect function against fault conditions, such as the over-voltage protection (OVP), LED OPEN and SHORT protection, the over current limit protection of DCDC (OCP). Therefore BD9422EFV is available for the fail-safe design over a wide range output voltage. ●Key Specification  Operating power supply voltage range: 9.0V to 35.0V  Oscillator frequency: 500kHz (RT=30kΩ)  Operating Current: 9mA (typ.)  Operating temperature range: -40°C to +85°C ●Applications TV, Computer Display, Notebook, LCD Backlighting ●Typical Application Circuit ●Features ■ 6ch Constant LED drivers, available 400mA drive per 1ch. ■ Constant current...
