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.
Available in 8-pin MSOP and SOIC packaging, the MIC384 features one local and two remote temperature measurement zones, I2C/SMBus compatibility, a programmable interrupt output, and an address selection input.
"The MIC384 leverages Micrel's unique ability to interface to a remote thermal diode using only a single IC pin", says Jim Judkins, Product Marketing Manager.
"It allowed us to pack more features into a smaller, lower-cost package.
Cost and space are at a premium in virtually every application today".
Judkins continues: "Micrel has created a proprietary analogue-digital convertor and signal processing front-end which can accomplish thermal diode measurements using only one wire and ground.
In fact, our testing has shown that our one-wire implementation is capable of accuracy and noise performance as good or better than competing two-wire implementations".
The MIC384's operating power supply current is a portable-friendly 0.35mA, and the quiescent current in shutdown mode is only 1.0uA.
Two package options are available.
In 1000 piece quantities, the MIC384BM in 8-pin SOIC packaging is priced at $1.54 each.
The MSOP-08 MIC384BMM is $1.66 in 1000 piece quantities.
SOIC samples are from stock.
An evaluation board will be available shortly.
