Product Overview
LTC3785 is a high power synchronous buck-boost controller. It 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, this device 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, short-circuit and overvoltage protection. It is widely used in application such as palmtop computers, handheld instruments, wireless modems, cellular telephones etc.
- Upto 96% efficiency
- Upto 10A of output current
- All N-channel MOSFETs, No RSENSE™
- True output disconnect during shutdown
- Selectable Burst Mode® operation
- Quiescent current (shutdown) is 15µA typical at (RUN/SS = 0V, ISVOUT = 3.6V)
- Feedback voltage is 1.225V typical at (TA = 25°C, VIN = ISVOUT = VDRV = VBST1 = VBST2 = 3.6V)
- Maximum duty cycle is 90% typical at (boost, % switch BG2 On)
- Operating junction temperature is -40°C to 85°C
- Package style is 24-lead plastic QFN
