Introduction
The LTC3785 is a high power synchronous buck-boost controller that drives all N-channel power MOSFETs from input voltages above, below and equal to the output voltage. With an input range of 2.7V to 10V, the LTC3785 is well suited for a wide variety of single or dual cell Li-Ion or multicell alkaline/NiMH applications. The operating frequency can be programmed from 100kHz to 1MHz. The soft-start time and current limit are also programmable. The soft-start capacitor doubles as the fault timer which can program the IC to latch off or recycle after a determined off time. Burst Mode operation is user controlled and can be enabled by driving the MODE pin high. Protection features include foldback current limit, shortcircuit and overvoltage protection.
Features
- Single Inductor Architecture Allows VIN Above, Below or Equal to VOUT
- 2.7V to 10V Input and Output Range
- Up to 96% Efficiency
- Up to 10A of Output Current
- All N-channel MOSFETs, No RSENSE
- True Output Disconnect During Shutdown
- Programmable Current Limit and Soft-Start
- Optional Short-Circuit Shutdown Timer
- Output Overvoltage and Undervoltage Protection
- Programmable Frequency: 100kHz to 1MHz
- Selectable Burst Mode Operation
- Available in 24-Lead (4mm×4mm) Exposed Pad QFN Package
Applications
- Palmtop Computers
- Handheld Instruments
- Wireless Modems
- Cellular Telephones
