Microchip Technology MIC2810-1J6SYML-TR

Overview

MIC2810-1J6SYML-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 (LDO1: 1.4 V, LDO2: 3.3 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 DC/DC output noise, and operates across –40°C to +125°C for embedded MPU power in portable and RF-sensitive systems.

For engineers reviewing the MIC2810-1J6SYML-TR datasheet, MIC2810-1J6SYML-TR pinout, MIC2810-1J6SYML-TR application, or MIC2810-1J6SYML-TR equivalent, this page provides verified specifications, validated pin functions, confirmed thermal and noise performance in both PWM and LOWQ modes, and real-world sequencing behavior for backup-power-aware designs.

Technical Context

The MIC2810-1J6SYML-TR implements a dual-mode regulation architecture: full-power 2 MHz PWM operation for high-efficiency 600 mA loads, and LOWQ linear-mode operation where the DC/DC is disabled and output is sourced via LDO path with 53 µVRMS noise and <30 µA IQ. Its POR circuit uses a programmable CSET capacitor to set delay time (up to 1 s) and performs logic-OR monitoring across all three outputs.

Pin-level isolation enables leakage-free interfacing with host MPUs under backup power: the open-drain POR output lacks clamping diodes to supply rails, allowing safe pull-up to auxiliary domains; EN/EN1/EN2 are CMOS inputs requiring ≥1.0 V logic high, while LOWQ is active-low with defined 0.2 V/1.0 V thresholds. Thermal shutdown activates at 160°C with 23°C hysteresis.

FAQ

What output voltages does the MIC2810-1J6SYML-TR provide?

The MIC2810-1J6SYML-TR delivers three fixed output voltages: 1.25 V from the DC/DC converter, 1.4 V from LDO1, and 3.3 V from LDO2 - as confirmed by Microchip's Product Identification System ('1J6S' suffix). All outputs are independently enabled and support precise sequencing via dedicated EN pins.

How does the LOWQ mode affect the DC/DC converter and LDOs in the MIC2810-1J6SYML-TR?

In LOWQ mode (LOWQ pin ≤ 0.2 V), the MIC2810-1J6SYML-TR disables the DC/DC PWM circuitry and routes output through the LDO path, reducing total quiescent current to <30 µA and lowering DC/DC output noise to 53 µVRMS. LDO1 and LDO2 current limits are reduced to <50 mA each, and the SW pin becomes high-impedance.

Can the MIC2810-1J6SYML-TR POR output be safely pulled up to a backup power rail?

Yes - the MIC2810-1J6SYML-TR POR pin is an open-drain output with no internal clamping diodes to VIN or other supplies, enabling direct pull-up to a backup domain (e.g., coin cell or supercap) without parasitic leakage. This ensures valid reset signaling even when main power is removed.

What is the purpose of the CSET pin on the MIC2810-1J6SYML-TR, and how is it configured?

The CSET pin on the MIC2810-1J6SYML-TR sources a 1.25 µA current to charge an external capacitor to 1.25 V, setting the POR assertion delay time in microseconds equal to the capacitor value in picofarads (e.g., 100 nF = 100,000 pF = 100,000 µs delay). Leaving CSET open yields minimum delay; grounding is prohibited.

Does the MIC2810-1J6SYML-TR support independent enable control for all three regulators?

Yes - the MIC2810-1J6SYML-TR provides fully independent enable control: EN for the DC/DC converter, EN1 for LDO1, and EN2 for LDO2. Each is an active-high CMOS input with defined logic thresholds (VIH ≥ 1.0 V, VIL ≤ 0.2 V), and all must be actively driven - floating is prohibited per datasheet guidance.
