The SID1102K is the latest member of the SCALE-iDriver family and provides N-channel drive for both the low and high side booster MOSFET switches which reduces system cost, minimises switching losses and increases power capability. It delivers a peak drive current of up to 5A to drive 300A switches without boosters. External boosters can be used to cost-effectively scale gate current up to 60A peak.
Reinforced galvanic isolation is provided by Power Integrations’ solid insulator FluxLink technology which eliminates the need for optocouplers, improving reliability and ruggedness. SCALE-iDriver technology simplifies design and manufacturing by reducing the bill of material (BOM) count as complete drivers can be built using a SID1102K driver and just eight external components. Devices deliver system-level protection features including under-voltage lock-out, rail-to-rail stabilised output voltage – from a single supply rail, high common-mode transient immunity and 9.4 mm creepage and clearance.
“The SID1102K gate-driver IC reduces time-to-market for designers by providing an easy-to-implement, scalable solution which includes critical safety and protection features in a single, compact, robust package,” said Michael Hornkamp, senior director of marketing for gate-driver products at Power Integrations.
Key applications include UPS, standard AC drives and VFDs, photovoltaic/ solar systems, commercial air conditioners, DC chargers and welding equipment. Devices are available now priced at $1.52 in 10,000 piece quantities. Technical support for SID1102K ICs is available from the Power Integrations at
