LT1076HV - Step-Down Switching Regulator

The LT1074 is a 5A LT1076 is rated at 2A) 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 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 LT1074 to drive a tapped-inductor in the buck mode with output currents up to 10A.
The LT1074 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, 4e8 dynamic behavior of the Regulator is significantly improved over previous designs.
On-chip pulse by pulse current limiting makes the LT1074 nearly bust-proof for 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 LT1074 is available in lowcost TO-220 or DD packages with frequency pre-set at 100kHz and current limit at 6.5A LT1076 =2.6A). A 7-pin TO-220 package is also available which allows current limit to be adjusted down to zero. In addition, full micropower shutdown CAN be programmed. See Application Note 44 for design details.
A fixed 5V output, 2A version is also available. See LT1076-5.
