Power management IC integrates buck regulator and LDO

San Jose, Calif. — Micrel Inc. has launched an ultra-small dual channel power management IC that provides two high-performance outputs for portable device applications including smart phones, GPS devices, and digital still cameras. The MIC2225 integrates a 2-MHz synchronous buck regulator with an independent 300 mA LDO in an ultra-small package that the company claims is the industry's smallest combo buck regulator/LDO.

The MIC2225 is suitable for applications where an additional set of voltages is needed to support an applications processor or co-processor. The combination of the 600 mA DC-to-DC and 300 mA linear regulator permits the use of small value inductors and capacitors that reduce board space, supports continuous load currents up to 600 mA, and achieves more than 90 percent efficiency., said Micrel.

Fixed output voltage options are available down to 1 V on the DC-to-DC converter and 0.8 V on the LDO. The unique PWM architecture also offers fast transient response, high efficiency and low output ripple, said Micrel. The MIC2225 is housed in a small leadless 10-pin, 2 x 2-mm thin MLF with a junction range temperature from -40°C to +125°C.

Pricing: $1.30 in quantities of 1,000
Availability: Available in volume production.
