Description

The SG3526DW is a DC-to-DC switching controller designed for high-efficiency power supply applications. It operates on a voltage range of 8 to 35 volts and features a 5V reference that is trimmed to ±1%. The oscillator range is adjustable from 1Hz to 350KHz. The device has dual 100mA source/sink outputs and digital current limiting. It also offers double pulse suppression, programmable deadtime, undervoltage lockout, single pulse metering, programmable soft-start, wide current limit common mode range, TTL/CMOS compatible logic ports, and symmetry correction capability. Additionally, the SG3526DW guarantees 6-unit synchronization. It is commonly used in military and industrial applications owing to its high-reliability features such as radiation data availability and LMI Level "S" processing.
