MOTOROLA ANALOG IC DEVICE DATA
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
μ
A.
Output Switch Current in Excess of 5.0 A
Fixed Frequency Oscillator (72 kHz) with On–Chip Timing
Provides 5.05 V Output without External Resistor Divider
