World's simplest buck regulator boosted to 2A
Micrel has boosted the output capability of the industry's simplest surface-mount DC/DC switching convertor to 2A while retaining the device's original SO-8 packaging.
Dual and triple 135MHz low-power op amps
Consuming just 2.4mA per op amp, the MIC915 dual and MIC916 triple op amps extend Micrel's premier family of high-speed, low-power op amps for power-sensitive high-speed applications.
The MIC2225 is suitable for applications where an additional set of voltages is needed to support an applications processor or co-processor.
"The MIC2225 addresses three major concerns in today's portable electronic market: performance, size, and cost", said Ralf Muenster, Micrel's Marketing Director for Power Products.
"With high efficiency and a small board area, circuit designers will find the MIC2225 an optimally balanced solution for converged portable devices that require more than one processor".
The combination of the 600mA DC-to-DC plus 300mA linear regulator permits the use of small value inductors and capacitors that reduce board space, support continuous load currents up to 600mA, and achieve more than 90% efficiency.
The MIC2225 employs a micron cap design which allows stable operation with very small ceramic output capacitors and a small inductor.
This reduces the board space required and the external component cost.
Fixed output voltages options are available down to 1V on the DC-to-DC convertor and 0.8V on the LDO.
The PWM architecture also offers fast transient response, high efficiency and low output ripple.
The package is a leadless 10-pin 2 x 2mm thin MLF with a junction range temperature from -40C to +125C.
