INVERTING SWITCHING
REGULATORS
 DESCRIPTION
The UTC UMC33167 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 36μA.
 FEATURES
* Output Switch Current in Excess of 5.0A
* Fixed Frequency Oscillator (72kHz) with On-Chip Timing
* Provides 5.05V Output without External Resistor Divider
* Precision 2% Reference
* 0% ~ 95% Output Duty Cycle
* Cycle-by-Cycle Current Limiting
* Undervoltage Lockout with Hysteresis
* Internal Thermal Shutdown
* Operation from 7.5V ~ 40V
* Standby Mode Reduces Power Supply Current to 36μA
