5.0 A, Step−Up/Down/
Inverting Switching
Regulators
The MC34167, MC33167 series are high performance fixed
frequency power switching regulators that contain the primary
functions required for dc−to−dc converters. This series was
specifically designed to be incorporated in step−down and
voltage−inverting configurations with a minimum number of external
components and can also be used cost effectively in step−up
applications.
These devices consist of an internal temperature compensated
reference, fixed frequency oscillator with on−chip timing components,
latching pulse width modulator for single pulse metering, high gain
error amplifier, and a high current output switch.
Protective features consist of cycle−by−cycle current limiting,
undervoltage lockout, and thermal shutdown. Also included is a low
power standby mode that reduces power supply current to 36
mA.
