MIC2810 Digital Power Management IC 2 MHz, 600 mA DC/DC with Dual 300 mA/300 mA Low V LDOs IN Features General Description 2.7V to 5.5V Input Voltage Range The MIC2810 is a high performance power management IC, featuring three output voltages with 2 MHz DC/DC Converter and Two LDOs independent enable control: a 2 MHz DC/DC converter Integrated Power-on Reset (POR) and two 300mA LDOs. The MIC2810 features a Adjustable POR Delay Time LOWQ mode, reducing the total current draw while in LOWQ Mode this mode to less than 30 A. In LOWQ mode, the -30 A Total I When in LOWQ Mode output noise of the DC/DC converter is 53 V , Q RMS DC/DC Converter significantly lower than other converters that use a PFM light load mode that can interfere with sensitive - Up to 600 mA of Output Current in PWM RF circuitry. Mode The DC/DC converter uses small values of L and C to Mode: No Ripple Light Load Mode -LOWQ reduce board space but still retains high efficiency over -53V Output Noise in LOWQ Mode RMS a wide load range, while supporting load currents up to - 2 MHz PWM Mode Operation 600 mA. - >90% Efficiency The LDOs operate with very small ceramic output LDO1 capacitors for stability, therefore, reducing required - 1.65V to 5.5V Input Voltage Range board space and component cost. It is available in - 300 mA Output Current various output voltage options in the 16-pin 3 mm x - Output Voltage Down to 0.8V 3 mm QFN leadless package.
