TOKYO--(BUSINESS WIRE)--Toshiba Corporation (TOKYO:6502) today announced the launch of “TC7735FTG”, a system power supply IC for the medium-sized LCD modules that are mainly used in car navigation systems. Sample shipments start today.
LCD modules require maximum five different voltage power supplies to drive the controller and drivers. The IC integrates 2 channels of DC-DC converters, 2 channels of charge pumps, and one operational amplifier. This allows LCD modules to be driven with a single chip, reducing mounting area. The product also supports a wide operational voltage range from 4.5 to 16V, which enables direct power supply from car batteries and allows for use in car navigation systems.
The IC integrates an OTP memory1, allowing it to store different power control set-up data for each LCD modules.
Key Features
- Built-in 5 different power outputs.
- Supports wide operating voltage range from 4.5 to 16V.
- Adopts automatic buck-boost converter that identifies input voltage and selects operation mode (buck or boost), eliminating control by external command.
- Built-in OTP for adjustable power control of each LCD.
