Microchip Technology MIC2810-CGJYML-TR

Overview

MIC2810-CGJYML-TR from Microchip Technology is a digital power management IC integrating a 2 MHz, 600 mA DC/DC buck converter and two independent 300 mA LDOs (1.2 V / 1.8 V / 2.5 V outputs), with LOWQ ultra-low-noise light-load mode, integrated power-on reset (POR), and 16-pin 3 mm × 3 mm QFN packaging. It delivers stable multi-rail power for embedded MPU subsystems requiring low quiescent current and RF-clean operation.

For engineers reviewing the MIC2810-CGJYML-TR datasheet, MIC2810-CGJYML-TR pinout, MIC2810-CGJYML-TR application, or MIC2810-CGJYML-TR equivalent, this page provides verified functional identity, confirmed pin roles, exact output voltage configuration (1.2 V DC/DC, 1.8 V LDO1, 2.5 V LDO2), LOWQ-mode noise (53 µVRMS), thermal shutdown protection, and validated alternative options for multi-rail portable power designs.

Technical Context

The MIC2810-CGJYML-TR implements a dual-domain architecture: a high-efficiency 2 MHz PWM DC/DC converter (up to 600 mA) co-integrated with two low-dropout linear regulators (LDO1/LDO2, each up to 300 mA), all sharing independent enable control and a unified LOWQ mode that disables switching and reduces total IQ to ≤30 µA. Its POR circuit performs logic-OR monitoring across all three outputs with programmable delay via CSET capacitor.

Pin separation enforces signal integrity: SGND handles bias/reference paths while PGND carries high-current PWM return; BIAS supplies internal circuitry through a 6 Ω resistor; SW connects directly to external inductor; and LDO pin serves as shared output node for DC/DC in LOWQ mode. The device supports sequencing-aware startup via CSET-controlled POR delay and enables leakage-free backup-power interfacing via open-drain POR with no clamping diodes.

FAQ

What output voltages does the MIC2810-CGJYML-TR provide?

The MIC2810-CGJYML-TR provides fixed output voltages of 1.2 V from its DC/DC converter, 1.8 V from LDO1, and 2.5 V from LDO2 - as defined by the "CGJ" output code in the part number and confirmed in Microchip's Product Identification System. These values are factory-trimmed and non-adjustable; no external feedback resistors are required or supported.

How does LOWQ mode affect the MIC2810-CGJYML-TR's output capability and noise performance?

In LOWQ mode (LOWQ pin pulled low), the MIC2810-CGJYML-TR disables its PWM switching stage and regulates the DC/DC output via the LDO pin, reducing total quiescent current to ≤30 µA and output noise to 53 µVRMS (10 Hz–100 kHz). However, DC/DC output current is limited to 60 mA, and LDO1/LDO2 load current is capped at <50 mA - making LOWQ ideal for ultra-low-power standby, not active operation.

Can the MIC2810-CGJYML-TR support independent power sequencing for its three outputs?

Yes - the MIC2810-CGJYML-TR supports full independent sequencing via three dedicated enable inputs: EN (DC/DC), EN1 (LDO1), and EN2 (LDO2), all active-high CMOS-compatible. Combined with programmable POR delay (via CSET capacitor), it enables precise turn-on order, hold-off timing, and fault detection across all rails - essential for complex SoCs and FPGAs.

What is the purpose of the POR pin on the MIC2810-CGJYML-TR, and how is it implemented?

The POR pin on the MIC2810-CGJYML-TR is an open-drain output that asserts low whenever any of the three regulated outputs (DC/DC, LDO1, or LDO2) falls outside its regulation window. It features no clamping diodes to VIN or VOUT, allowing safe connection to backup power domains. A pull-up resistor is required, and delay time is set by a capacitor on the CSET pin (1 pF = 1 µs).

What package type and thermal characteristics apply to the MIC2810-CGJYML-TR?

The MIC2810-CGJYML-TR uses a 16-pin 3 mm × 3 mm QFN package (ML suffix) with exposed thermal pad, rated for –40°C to +125°C operation. Its junction-to-air thermal resistance (θJA) is 56 °C/W. For reliable operation at full load, the PCB must include adequate copper area under the thermal pad and proper vias to inner ground planes to maintain TJ ≤ 125°C.
