Linear Technology LT1176

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. The input voltage range as a buck converter is 8V to 35V, but a selfboot feature allows input voltages as low as 5V in the inverting and boost configurations.

FEATURES

s s s s s s s s 1.2A On-Board Switch 100kHz Switching Frequency Excellent Dynamic Behavior DIP and Surface Mount Packages Only 8mA Quiescent Current Preset 5V Output Available Operates Up to 35V Input Micropower Shutdown Mode tion. 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. 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 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.
