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.
Competing op amps at this speed consume 200uA or more.
Micrel claims only its own MIC820 provides a comparable speed/power combination.
Packaging is Micrel's Teeny SC70-5, which is approximately half the size of the SOT23-5 packaging offered for competing devices.
"The MIC820 set a new standard for low power op amps, achieving 1/10th the power consumption of similar-speed devices", said Scott Brown, Linear and RF Business Unit Manager.
"The new MIC860 consumes similar power to the MIC820 but operates down to lower voltages, has improved PSRR, CMRR and open-loop gain".
The MIC860 is unity-gain stable.
It is specified at supply voltages of 2.7 and 5V.
Input offset voltage is 5mV (typical), large-signal voltage gain is 91dB, PSRR is 79dB and CMRR is 77dB.
The MIC860 is provided in SC70-5 packaging and priced at $1.02 in 1000-off quantities.
