Description
This IC is designed as general purpose multi-function DC/DC converter and is optimum also for back-light control for
LCD. Small 10-pin package containing many functions simplifies peripheral circuits and set design.
Priority control circuit contained in 2 channel input allows for simpler control when back-light is on and during the
stable state.
Features
• Wide operating voltage range: 8.6 to 25 V
• High precision reference voltage: 5 V ± 1%
• 2 channel priority control operation ("High" input prioritized)
• High speed switching operation (500 kHz)
• Output short-circuit protection circuit, ON/OFF control, Dead time control, Soft start operation.
• Small size 10-pin SOP package
• High speed pulse-by-pulse current limit
• Totem-pole output stage
Output current I_O (peak): ±1 A
Application
Back-light control for general electronic products such as personal computers, word processors, and portable
equipments.
