Silicon General/Microsemi - SG1526J/883B, NSN 5962-01-148-3373 - IC, Switching Controller 0.2A Pulse Width Modulation 350 kHz MIL spec. RFE.
Silicon General/Microsemi - SG1526J/883B, NSN 5962-01-148-3373
0.2A SWITCHING DC CONTROLLER, IC Reg buck/Flyback, 350kHz SWITCHING FREQ-MAX, Step-down - Step-up
IC, High Reliability Isolated Switching Regulator, Regulating Pulse Width Modulator. Package: CDIP18, test dots.
Note: Military cage No. 34333. Used/Perfect socket pulls.
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 under-voltage lockout, digital current limiting, double pulse inhibit, a data latch for single pulse metering, adjustable dead-time, 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 transformer-less 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.
