Regulating Pulse Width Modulator

The UC1526 is a high performance monolithic pulse width Modulator circuit designed for fixed-frequency Switching Regulators and other power control applications. Included in an 18-pin dual-in-line package are a temperature compensated Voltage Reference sawtooth Oscillator error Amplifier pulse width Modulator pulse metering and setting Logic and two low impedance Power Drivers Also included are protective features such as soft-start and under-voltage lockout, digital current limiting, double pulse inhibit, a data latch for single pulse metering, adjustable deadtime, and provision for symmetry correction inputs. For ease of Interface all digital control ports are TTL and B-series CMOS compatible. Active LOW Logic design allows wired-OR connections for maximum flexibility. This versatile device CAN be used to implement single-ended or push-pull Switching Regulators of either polarity, both transformerless and transformer coupled. The UC1526 is characterized for operation over the full military temperature range of -55C to +125C. The UC2526 is characterized for operation from -25C to +85C, and the UC3526 is characterized for operation from 0 to +70C.
