New Gate Drivers From Power Integrations Deliver Up To 5 A


Power Integrations has introduced the newest member of its
SCALE-iDriver IC family, SID1102K, a single-channel, isolated, IGBT and MOSFET
gate driver in a wide-body eSOP package. Featuring a peak drive current of up
to 5 A, the new part is able to drive 300 A switches without boosters; external
boosters can be used to cost-effectively scale gate current up to 60 A peak.
This device provides N-channel drive for both the low and high side booster
MOSFET switches which reduces system cost, minimizes switching losses and
increases power capability.

Reinforced galvanic isolation is provided by Power
Integrations' innovative, solid insulator FluxLink technology which eliminates
the need for optocouplers, improving reliability and ruggedness. SCALE-iDriver
technology simplifies design and manufacturing by reducing BOM count; complete
drivers can be built using a SID1102K IC and just eight external components.
Devices deliver system-level protection features including under-voltage
lock-out, rail-to-rail stabilized output voltage - from a single supply rail,
high common-mode transient immunity and 9.4 mm creepage and clearance.

Comments Michael Hornkamp, senior director of marketing for
gate-driver products at Power Integrations: "The new 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."

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
