Inverting Switching
Regulators
The MC34166, MC33166 series are high performance fixed
frequency power switching regulators that contain the primary
functions required for dctodc converters. This series was specifically
designed to be incorporated in stepdown and voltageinverting
configurations with a minimum number of external components and
can also be used cost effectively in stepup applications.
These devices consist of an internal temperature compensated
reference, fixed frequency oscillator with onchip timing components,
latching pulse width modulator for single pulse metering, high gain
error amplifier, and a high current output switch.
Protective features consist of cyclebycycle current limiting,
undervoltage lockout, and thermal shutdown. Also included is a low
power standby mode that reduces power supply current to 36 A.
