Product Overview
LTC3775 is a high efficiency synchronous step-down switching DC/DC controller. It drives an all N-channel power MOSFET stage from a 4.5V to 38V input supply voltage. A patented line feedforward compensation circuit and a high bandwidth error amplifier provide very fast line and load transient response. High step-down ratios are made possible by a low 30ns Minimum on-time, allowing extremely low duty cycles. MOSFET RDS(ON) current sensing maximizes efficiency. Alternatively, a sense resistor can be used for higher current limit accuracy. Continuous monitoring of the voltages across the top and bottom MOSFETs allows cycle-by-cycle control of the inductor current, configurable by external resistors. The soft-start function controls the duty cycle during start-up, providing a smooth output voltage ramp up. It is used in application such as automotive systems, telecom and industrial power supplies, point of load applications etc.
- Line feedforward compensation
- Powerful on-board MOSFET drivers
- Leading edge modulation voltage mode control

- Selectable pulse-skipping or forced continuous modes of operation
- Low shutdown current is 14μA typical at (TA = 25°C, VIN = 12V, VRUN = 5V)
- Feedback pin voltage is 0.6V typical at (TA = 25°C, VIN = 12V, VRUN = 5V)
- Operating temperature is -40°C to 85°C
- Package style is 16-lead plastic MSOP
