Microchip MIC2800-G1JJYML-TR DC-DC Converter, 2 Linear Regulators, LowQ Mode, POR, VQFN

Technical description of the product (MIC2800-G1JJYML-TR):

The MIC2800 is a high-performance power management IC, providing three output voltages with maximum efficiency. Integrating a 2MHz DC/DC converter with an LDO post regulator, the MIC2800 offers two high-efficiency outputs with a second, 300mA LDO for maximum flexibility. The MIC2800 features a LowQ® mode, reducing the total current draw while in this mode to less than 30µA. In LowQ® mode, the output noise of the DC/DC converter is 75µVRMS, significantly lower than other converters which use a PFM light load mode that can interfere with sensitive RF circuitry. The DC/DC converter uses small values of L and C to reduce board space but still retains efficiencies over 90% at load currents up to 600mA. The MIC2800 is a μCap design, operating with very small ceramic output capacitors and inductors for stability, reducing required board space and component cost. Features: 2.7V to 5.5V input voltage range, LDO1: Low input voltage is powered directly from DC/DC converter for highest efficiency, Adjustable delay time, 30µA Total IQ when in LowQ® mode, Output current to 600mA in PWM mode, 75µVRMS output noise in LowQ® mode.
