Microchip Technology MIC2810-1J6JYML-TR

Overview

MIC2810-1J6JYML-TR from Microchip Technology is a highly integrated digital power management IC featuring a 2 MHz, 600 mA DC/DC buck converter and two independent 300 mA low-dropout regulators (LDO1 = 1.4 V, LDO2 = 2.5 V, DC/DC = 1.25 V), all with individual enable control and LOWQ ultra-low-noise light-load mode. It delivers <30 µA total quiescent current in LOWQ mode, 53 µVRMS output noise on the DC/DC rail, and operates across –40°C to +125°C in a 3 mm × 3 mm QFN package - ideal for space-constrained, battery-powered MPU/MCU subsystems requiring clean, sequenced, multi-rail power.

For engineers reviewing the MIC2810-1J6JYML-TR datasheet, MIC2810-1J6JYML-TR pinout, MIC2810-1J6JYML-TR application, or MIC2810-1J6JYML-TR equivalent, this page provides verified technical context, validated pin functions, confirmed low-noise performance metrics in both PWM and LOWQ modes, real-world sequencing behavior of its POR and CSET pins, and direct alternative options with documented functional trade-offs.

Technical Context

The MIC2810-1J6JYML-TR integrates three regulated outputs - one synchronous buck converter (1.25 V) and two LDOs (1.4 V and 2.5 V) - each with independent CMOS enable inputs (EN, EN1, EN2) and shared LOWQ mode control. Its dual-ground architecture separates signal ground (SGND) and power ground (PGND) to minimize noise coupling between control circuitry and high-current switching paths.

LOWQ mode disables the PWM switcher and reconfigures the DC/DC output to be sourced through an internal linear regulator path (LDO pin), reducing total IQ to ≤30 µA while maintaining regulation at up to 60 mA load; simultaneously, LDO1/LDO2 current limits are reduced to <50 mA. The open-drain POR output performs a logic-OR monitoring of all three outputs and supports programmable delay (via CSET capacitor) for reliable power sequencing in multi-rail systems.

FAQ

What is the exact output voltage configuration of the MIC2810-1J6JYML-TR?

The MIC2810-1J6JYML-TR is factory-configured with fixed output voltages: DC/DC buck converter = 1.25 V, LDO1 = 1.4 V, and LDO2 = 2.5 V. These values are encoded in the "1J6J" suffix per Microchip's Product Identification System and are non-adjustable. Each rail operates independently under its respective enable pin (EN, EN1, EN2), and all three are monitored by the shared POR output.

How does the LOWQ mode affect output current capability on each rail of the MIC2810-1J6JYML-TR?

In LOWQ mode (LOWQ pin ≤ 0.2 V), the MIC2810-1J6JYML-TR disables the PWM switcher and routes the DC/DC output through the LDO pin, limiting that rail to 60 mA. Simultaneously, LDO1 and LDO2 current limits are reduced to <50 mA each. In contrast, full-power (LOWQ ≥ 1.0 V) mode restores 600 mA for the DC/DC converter and 300 mA for each LDO - enabling dynamic load adaptation based on system activity.

Can the POR output of the MIC2810-1J6JYML-TR be safely pulled up to a backup power domain?

Yes - the POR output of the MIC2810-1J6JYML-TR uses an open-drain N-channel structure with no ESD clamping diodes to VIN or other supplies. This design allows the POR pin to be pulled up to a backup voltage (e.g., coin-cell or supercap) without parasitic leakage, even when main power is removed. It ensures reliable reset assertion during brownout or power-fail events in always-on systems.

What is the recommended capacitor value for setting a 200 ms POR delay on the MIC2810-1J6JYML-TR?

Per Equation 3-1 in the datasheet, the CSET pin charges an external capacitor at 1.25 µA, and the delay (in µs) equals the capacitance (in pF). For a 200 ms (200,000 µs) delay, a 200 nF capacitor is required (200,000 pF = 200 nF). Use a stable X7R/X5R ceramic capacitor rated for ≥6.3 V and place it close to the CSET pin and SGND - grounding CSET is prohibited.

Does the MIC2810-1J6JYML-TR require external compensation components for stability?

No - the MIC2810-1J6JYML-TR is internally compensated and requires only the specified external passive components: 2.2 µF ceramic output capacitors per rail (LDO1, LDO2, DC/DC), a 4.7 µF input capacitor on VIN, and a 2.2 µH shielded inductor. No external compensation network (e.g., RC snubbers or type-II/III compensators) is needed, simplifying design and reducing bill-of-materials cost.
