Intersil claims industry's highest performance integrated buck-boost regulator

August 22, 2011 | Paul Buckley | 222903223
Intersil Corporation has developed a compact, high-efficiency 1.2 A buck-boost regulator that uses a proprietary H-Bridge Buck-Boost control architecture. The ISL9110's compact size makes it ideal for battery-powered devices such as handheld instruments, games, point-of-sale systems and similar applications.

The ISL9110 simplifies design by providing a regulated output voltage from an input that can be either above or below the output voltage. The regulator minimizes external components, requiring just a single inductor and two capacitors. It also features the industry's lowest voltage deviation during transitions between buck and boost modes, providing designers with flexibility in selecting the optimal output voltage. The ISL9110's 2.5 MHz switching frequency is also the highest available in a buck-boost regulator, further minimizing external component sizes.

The device can deliver more than 2 A at 2 Vout or 1.2 A at 3.0 Vout from a single Li-Ion battery (the industry's highest current capability in a tiny 3x3 mm footprint). External feedback resistors can set the output voltage on the ISL9110's adjustable version to deliver output voltages as low as 1 V, an important capability for loads such as RF power amplifiers.

Availability and Pricing

The ISL9110 buck-boost regulator is available now in a compact 12-pin, 3x3 mm TDFN package with either fixed output voltages of 3.3 V or 5.0 V, or with an adjustable output. Pricing starts at $2.08 each in 1,000-piece quantities.
