MIC2295 - High Power Density 1.2A Boost Regulator
High Power Density 1.2A
Boost Regulator General Description Features The MIC2295 is a 1.2Mhz, PWM dc/dc boost switching
regulator available in low profile Thin SOT23 and 2mm x
2mm MLFв„ў package options. High power density is
achieved with the MIC2295вЂ™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 5lead package and a 2mm x2mm 8-lead MLFв„ў leadless
package. The 2mm x 2mm MLFв„ў package option has an
output over-voltage protection feature.
The MIC2295 has an operating junction temperature range
of вЂ“40В°C to +125В°C Applications R1
