MIC2601/2
1.2A, 1.2MHz/2MHz Wide Input Range
Integrated Switch Boost Regulator General Description Features The MIC2601/2 is a 1.2MHz/2MHz, PWM DC/DC boost
switching regulator available in a 2mm x 2mm MLFВ®
package. High power density is achieved with the
MIC2601/2’s internal 40V/1.2A switch, allowing it to power
large loads in a tiny footprint.
The
MIC2601/2
implements
constant
frequency
1.2MHz/2MHz PWM current mode control. The MIC2601/2
offers internal compensation that provides excellent
transient response and output regulation performance. The
high frequency operation saves board space by allowing
small, low-profile external components. The fixed
frequency PWM scheme also reduces spurious switching
noise and ripple to the input power source.
Soft start reduces in rush current and is programmable via
external capacitor.
The MIC2601/2 is available in a 2mm x 2mm 8-pin MLFВ®
leadless package. Both devices have an output overvoltage protection feature. …
