LTC3245IMSE#PBF

LTC3245 is a switched capacitor buck-boost DC/DC converter. This device uses switched capacitor fractional conversion to maintain regulation over a wide range of input voltage. Internal circuitry automatically selects the conversion ratio to optimize efficiency as input voltage and load conditions vary. No inductors are required. The unique constant frequency architecture provides a lower noise output than conventional charge pump regulators. To optimize efficiency at the expense of slightly higher output ripple, the device has pin selectable Burst Mode operation. It is widely used in application such as automotive ECU/CAN transceiver supplies, industrial housekeeping supplies, low power 12V to 5V conversion etc.

• Operating input voltage range is 2.7V to 38V
• Quiescent current is 18µA typical
• Multimode operation (2:1, 1:1, 1:2) with automatic mode switching
• Low noise, constant frequency operation
• Pin selectable burst mode® operation
• Over temperature and short-circuit protection
• Operating temperature is -40°C to 125°C
• Packaging style is 12-lead plastic MSOP
