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.
They require just 1.25mA of supply current and yet achieve 105 and 160MHz gain-bandwidth, respectively.
The MIC911 is heavily compensated to ensure ease of use; the MIC914 is uncompensated, yet unity-gain stable.
They complement the recently announced 135MHz, MIC910 and the 200MHz, MIC912 op amps.
"All these devices are capable of driving very large capacitance loads.
In fact the more capacitance there is, the more stable they get", says Scott Brown, Linear and RF Business Unit Manager.
"We are now taking their unique topology and producing lower power, slightly lower speed parts with the same ability to drive unlimited load capacitance".
All devices are specified at supply voltages of +/-2.5 and +/-9V.
The DC specifications of the new devices are equal to, or better than the earlier devices.
For example, input offset voltage is 1mV (typical), large signal voltage gain is 80dB, PSRR is 88dB and CMRR is a very impressive 112dB.
The MIC911BM5 and MIC914BM5 are manufactured in SOT23-5 packaging.
Both are priced at $1.40 each in 1K quantities.
