MC34166, MC33166
3.0 A, Step-Up/Down/
Inverting Switching
Regulators
The MC34166, MC33166 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. http://onsemi.com
