Analog Devices, Inc. 500kHz High Efficiency 6A Switching Regulator LT1370IR#PBF

Description
Product Details The LT1370 is a monolithic high frequency current mode switching regulator. It can be operated in all standard switching configurations including boost, buck, flyback, forward, inverting and “Cuk.” A 6A high efficiency switch is included on the die, along with all oscillator, control and protection circuitry. The LT1370 typically consumes only 4.5mA quiescent current and has higher efficiency than previous parts. High frequency switching allows for very small inductors to be used. New design techniques increase flexibility and maintain ease of use. Switching is easily synchronized to an external logic level source. A logic low on the Shutdown pin reduces supply current to 12µA. Unique error amplifier circuitry can regulate positive or negative output voltage while maintaining simple frequency compensation techniques. Nonlinear error amplifier transconductance reduces output overshoot on start-up or overload recovery. Oscillator frequency shifting protects external components during overload conditions.

A range of SEPIC DC-DC Converters from Linear Technology which can be used in applications where the output voltage may be either higher or lower than the input voltage. The SEPIC (Single-Ended Primary-Inductor Converter) topology also allows these converters to produce a negative output from a positive input voltage. Some of these switching regulators include features such as multiple outputs, programmable current limit, low battery detection and burst-mode operation.
