MIC2295
High Power Density 1.2A Boost Regulator
General Description
The MIC2295 is a 1.2Mhz, PWM dc/dc boost
switching regulator available in low profile Thin
SOT23 and 2mm x 2mm MLF package options.
High power density is achieved with the MIC2295’s
internal 34V / 1.2A switch, allowing it to power large
loads in a tiny footprint.
The MIC2295 implements constant frequency
1.2MHz PWM current mode control. The MIC2295
offers internal compensation that offers 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.
The MIC2295 is available in a low-profile Thin
SOT23 5-lead package and a 2mm x2mm 8-lead
MLF leadless package. The 2mm x 2mm MLF
package option has an output over-voltage
protection feature.
The MIC2295 has an operating junction temperature
range of –40
