The MC34167TVG 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. This device consists 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, under-voltage lockout and thermal shutdown. It also includes a low power standby mode that reduces power supply current to 36μA.
