description

® LT 1373 is a low-supply-current, high-frequency current-mode switching regulator. It can be used in all standard switching configurations, including boost, buck, reverse, forward, reverse and "CUK operated." "On the chip, along with all the oscillators, control and protection circuitry, including a 1.5A high-efficiency switch. All the features of the LT1373 in an 8-pin SO/PDIP package are integrated into. The 500kHz LT1372 typically consumes only 1 mA and has higher efficiency at 250kHz compared to the 4 mA at the shooting. The high switching frequency allows the use of small inductors to be used. All surface mount components consume less than 0.6 square inches of board space. New design technology for increased flexibility and ease of maintenance. Switch conveniently synchronizes to an external logic level source. The logic supply current on one low shutdown pin is reduced to 12μA. Unique error amplifier circuitry that adjusts positive or negative output voltage while maintaining simple frequency compensation technology. The transconductance of nonlinear error amplifiers reduces start-up or overload recovery output overshoot. Oscillator frequency shifts to protect external components in case of overload
