Analog Devices, Inc. 250kHz Low Supply Current High Efficiency 1.5A Switching Regulator LT1373CS8#PBF

Description
Product Details The LT1373 is a low supply current high frequency current mode switching regulator. It can be operated in all standard switching configurations including boost, buck, flyback, forward, inverting and “Cuk.” A 1.5A high efficiency switch is included on the die, along with all oscillator, control and protection circuitry. All functions of the LT1373 are integrated into 8-pin SO/PDIP packages. Compared to the 500kHz LT1372, which draws 4mA of quiescent current, the LT1373 switches at 250kHz, typically consumes only 1mA and has higher efficiency. High frequency switching allows for small inductors to be used. All surface mount components consume less than 0.6 square inch of board space. 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.

Linear Technology presents step-up (boost) switching regulators with both synchronous and non-synchronous internal switches. The high efficient DC-DC converters have a wide range of input voltages and switching frequencies. Some products feature unique properties that can help increase battery run time in handheld devices or even be managed in a range of switching configurations. Typical applications would be power inverters, fully floating multiple outputs and 5V logic supplies. For small circuit implementation Regulator Function = Boost/Buck Controller, Cuk, Flyback, Forward, Inverting Maximum Output Current = 1.5A Number of Outputs = 1 Line Regulation = 0.03 %/V Mounting Type = Surface Mount Package Type = SOIC Pin Count = 8 Maximum Switching Frequency = 290 kHz Switching Regulator = Yes Dimensions = 5.004 x 3.988 x 1.498mm Delivery on production packaging - Tube. This product is non-returnable.
