Overview
Regulating Pulse Width Modulator UC1526A UC2526A UC3526A FEATURES • Reduced Supply Current • Oscillator Frequency to 600kHz • Precision Band-Gap Reference • 7 to 35V Operation • Dual 200mA Source/Sink Outputs • Minimum Output Cross-Conduction • Double-Pulse Suppression Logic • Under-Voltage Lockout • Programmable Soft-Start • Thermal Shutdown • TTL/CMOS Compatible Logic Ports • 5 Volt Operation (VIN = VC = VREF = 5.
0V) DESCRIPTION The UC1526A Series are improved-performance pulse-width modulator circuits intended for direct replacement of equivalent non- “A” versions in all applications.
Higher frequency operation has been enhanced by several significant improvements including: a more accurate oscillator with less minimum dead time, reduced circuit delays (particularly in current limiting), and an improved output stage with negligible cross-conduction current.
Additional improvements include the incorporation of a precision, band-gap reference generator, reduced overall supply curre...
