LT1076-5 - 5V Step-Down Switching Regulator

The LT1076-5 is a 2A fixed 5V output monolithic bipolar Switching Regulator which requires only a few external parts for normal operation. The power Switch all Oscillator and control circuitry, all current limit components, and an output monitor are included on the chip. The topology is a classic positive buck configuration but several design innovations allow 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 40V below ground, allowing the LT1076-5 to drive a tapped inductor in the buck mode with output currents up to 4A.
The LT1076-5 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 LT1076-5 nearly bust-proof for 588 output overloads or shorts. The input voltage range as a buck converter is 8V to 60V, but a self-boot feature allows input voltages as low as 5V in the inverting and boost configurations.
The LT1076-5 is available in a low cost 5- and 7-lead TO-220 packages with frequency pre-set at 100kHz and current limit at 2.6A. See Application Note 44 for design details.
