Product Overview
LT3740 is a synchronous step-down switching regulator controller that drives N-channel power MOSFET stages. The controller uses valley current mode architecture to achieve very low duty cycles with excellent transient response without requiring a sense resistor. The XREF pin is an external reference input that allows the user to override the internal 0.8V feedback reference with any lower value, allowing full control of the output voltage during operation, output voltage tracking or soft-start. This device has three current limit levels that can be chosen by connecting the RANGE pin to ground, open, and input respectively. It is widely used in application such as notebook and palmtop computers, PDA, portable instruments, distributed power systems etc.
- Wide VIN range is 2.2V to 22V
- Internal boost provides 6V gate drive for VIN down to 2.2V
- No sensing resistor required
- Dual N-channel MOSFET synchronous drive
- Valley current mode control, optimized for high step-down ratio
- Power good output voltage monitor
- Three pin-selected current limit levels
- Internal boost switching frequency is 1MHz typical
- Input supply current is 0.6μA typical at (SHDN = 0V)
- Operating temperature is -40°C to 85°C, package style is 16-lead plastic DFN
