MIC2295YML-TR

MIC2295 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 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 5lead 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°C to +125°C • • • • • • • • • • • • • • Applications • • • • • • • • • R1 49.9k 2.2µF AGND L1 10µH PGND VOUT 5V/500mA MIC2295 BD5 MIC2295BML SW VIN OVP FB EN C1 2.2µF Organic EL power supplies 3.3V to 5V/500mA conversion TFT-LCD bias supplies Flash LED drivers Positive and negative output regulators SEPIC converters Positive to negative Cuk converters 12V supply for DSL applications Multi-output dc/dc converters VOUT 15V/100mA 10µH VIN 1-Cell Li Ion 3V to 4.2V 2.5V to 10V input voltage range Output voltage adjustable to 34V 1.2A switch current 1.2MHz PWM operation Stable with small size ceramic capacitors High efficiency Low input and output ripple
