LT1176/LT1176-5 Step-Down Switching Regulator 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. The LT1176 uses a true analog multiplier in the feedback loop.
