MIC2800-A4SYML-TR

The MIC2800-A4SYML-TR is a high-performance power management integrated circuit (PMIC) from Microchip Technology. It integrates a 2 MHz DC/DC converter with two LDO post-regulators, providing three output voltages with maximum efficiency. The device operates within a 2.7V to 5.5V input voltage range and features a 2 MHz PWM mode operation for the DC/DC converter, achieving over 90% efficiency at load currents up to 600 mA.

Key features include a LOWQ mode that reduces total current draw to less than 30 µA, and low output noise of 75 µVRMS in this mode. The LDO outputs are capable of 300 mA each. The MIC2800 is designed for applications requiring efficient power delivery, such as embedded MPU and MCU power, portable and wearable devices, and low-power RF systems. It is housed in a compact 16-pin 3mm x 3mm QFN package, suitable for space-constrained designs.

Additional integrated features include Power-on Reset (POR) with adjustable delay, thermal shutdown protection, and current limit protection, enhancing system reliability. The simple, leakage-free interfacing is ideal for applications with backup power systems.
