LT1176 - Step-Down Switching Regulator

The LT1176 is a 1A monolithic bipolar Switching Regulator which requires only a few external parts for normal operation. The power Switch all Oscillator and control circuitry, and all current limit components are included on the chip. The topology is a classic positive "buck" configuration but several design innovations allows this device to be used as a positive-to-negative converter, a negative boost converter, and as a flyback converter. The Switch output is specified to swing below ground. The LT1176 uses a true Analog Multiplier in the feedback loop.This makes the device respond nearly instantaneously to input voltage fluctuations and makes loop gain independent of input voltage. As a result, dynamic behavior of the Regulator is significantly improved over previous designs. On-chip pulse by pulse current limiting makes the LT1176 nearly bust-proof for output overloads or shorts. The input voltage range as a buck converter is 8V to 35V, but a self-boot feature allows input voltages as low as 5V in the inverting and boost configurations. The LT1176 is available in a low cost 8-lead DIP package with frequency preset at 100kHz and current limit at 1.7A An adjustable output is offered as well as a preset 5V version.
