Overview
Key Features: • 8 to 35 volt operation • 5V reference trimmed to ±1% • 1Hz to 350KHz oscillator range • Dual 100mA source/sink outputs • Digital current limiting • Double pulse suppression • Programmable deadtime • Undervoltage lockout • Single pulse metering • Programmable soft-start • Wide current limit common mode range • TTL/CMOS compatible logic ports • Symmetry correction capability • Guaranteed 6 unit synchronization The SG1526 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 steering logic, and two low impedance power drivers. Also included are protective features such as soft-start and undervoltage 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 SG1526 is characterized for operation over the full military ambient junction temperature range of -55°C to +150°C. The SG2526 is characterized for operation from -25°C to +150°C, and the SG3526 is characterized for operation from 0°C to +125°C. |
