ON Semi MC33166T 3.0 A, Step−Up/Down/Inverting Switching Regulator
Manufactured by ON Semiconductor - TO-220 5 pin package
DESCRIPTION
The MC33166 is a high performance fixed frequency power switching regulator that contains 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 36µA.
