Product details
Overview
MIC2810-4MSYML-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 = 1.2 V, LDO2 = 3.3 V), all with separate enable controls and operating across –40°C to +125°C. It features LOWQ mode for ultra-low-noise operation (53 µVRMS) and <30 µA total quiescent current, targeting embedded MPU power in space-constrained portable systems.
For engineers reviewing the MIC2810-4MSYML-TR datasheet, MIC2810-4MSYML-TR pinout, MIC2810-4MSYML-TR application, or MIC2810-4MSYML-TR equivalent, key selection considerations include triple-output sequencing control via CSET/POR, 3 mm × 3 mm QFN package constraints, dual-LDO input voltage flexibility (VIN1 down to 1.65 V), and LOWQ-mode noise-sensitive RF system compatibility.
Technical Context
The MIC2810-4MSYML-TR implements a hybrid regulation architecture: PWM switching (2 MHz, up to 600 mA) for high-efficiency main loads and linear LDOs (300 mA each) for low-noise rails, with shared bias circuitry powered via BIAS pin and segregated SGND/PGND paths. Its LOWQ mode disables the SW node and transitions DC/DC output regulation to the LDO pin, limiting LDO load to 60 mA while reducing IQ to ≤30 µA.
Power-on reset is implemented as an open-drain POR output with programmable delay (via CSET capacitor), performing logic-OR monitoring across all three outputs; it supports leakage-free interfacing to backup-power domains due to ESD-protected clamping-free design. The device uses internal current-source-based CSET timing (1.25 µA) and CMOS-compatible enable inputs (VIH ≥ 1.0 V, VIL ≤ 0.2 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | VIN/VIN2: 2.7–5.5 V; VIN1: 1.65–5.5 V - enables flexible supply partitioning for low-VIN LDO1 in battery-backed subsystems. |
| DC/DC Output Current | 600 mA (PWM mode); 60 mA (LOWQ mode) - supports dynamic load scaling between high-efficiency switching and ultra-low-noise linear regulation. |
| LDO Output Current | 300 mA per LDO (LDO1 = 1.2 V, LDO2 = 3.3 V) - delivers stable core and I/O rail power with dropout as low as 70 mV at 150 mA. |
| Quiescent Current | ≤30 µA total in LOWQ mode - extends battery life in always-on wearable or sensor nodes without compromising POR functionality. |
| Output Noise | 53 µVRMS (DC/DC, LOWQ mode, 10 Hz–100 kHz) - avoids interference with sensitive RF receivers (e.g., BLE, Zigbee) during light-load standby. |
| Switching Frequency | 2 MHz ±10% - permits use of compact 2.2 µH inductors and 2.2 µF ceramic capacitors, minimizing PCB area in portable designs. |
| POR Delay Programmability | CSET pin charges external capacitor at 1.25 µA; delay = CSET (pF) in µs - enables precise power-rail sequencing up to 1 second for multi-rail MPUs. |
Pinout & Package
Package: 16-pin, 3 mm × 3 mm, 0.85 mm height QFN (ML suffix), leadless, Pb-free, industrial temperature grade (–40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (LOWQ) | Mode control input | Active-low logic: LOW = LOWQ mode (30 µA IQ, LDO-regulated DC/DC output, 60 mA max); HIGH = PWM mode (600 mA, 2 MHz). |
| 2 (BIAS) | Bias supply input | Internal 6 Ω resistor-fed reference/bias rail; requires 0.1 µF bypass to SGND for stability and noise immunity. |
| 3 (SGND) | Signal ground | Low-current return path for control circuitry; must be routed separately from PGND to avoid noise coupling into POR/CSET. |
| 4 (PGND) | Power ground | High-current return for DC/DC switch node (SW); requires solid copper pour and short trace to minimize EMI and voltage drop. |
| 5 (SW) | Switch node output | Drives external inductor; high dv/dt node - must be kept away from analog/sensitive traces and minimized in loop area. |
| 6 (VIN) | Main input supply | Primary input for DC/DC controller, LDO1, LDO2 bias, and reference; requires 4.7 µF ceramic bypass to PGND. |
| 7 (VIN2) | LDO2 input supply | Dedicated input for LDO2; tied to VIN externally; supports same 2.7–5.5 V range as VIN. |
| 8 (LDO2) | LDO2 regulated output | Fixed 3.3 V output (per part number suffix); supplies I/O peripherals; requires 2.2 µF X7R/X5R ceramic capacitor. |
| 9 (LDO) | LDO-regulated DC/DC output | Connects to DC/DC VOUT in LOWQ mode only; provides clean 1.2 V rail when LOWQ = GND; not used in PWM mode. |
| 10 (VIN1) | LDO1 input supply | Independent input for LDO1; supports down to 1.65 V - enables direct connection to partially discharged batteries or secondary rails. |
| 11 (LDO1) | LDO1 regulated output | Fixed 1.2 V output (per part number suffix); powers MPU cores; requires 2.2 µF X7R/X5R ceramic capacitor. |
| 12 (POR) | Open-drain reset output | Asserts low if any output (DC/DC, LDO1, LDO2) falls below 90–99% of nominal; requires external pull-up for host MPU reset signaling. |
| 13 (CSET) | POR delay timing input | 1.25 µA current source charges external capacitor; sets POR assertion delay (1 pF = 1 µs); cannot be grounded. |
| 14 (EN1) | LDO1 enable input | CMOS-compatible active-high control (VIH ≥ 1.0 V); enables/disables LDO1 independently for power domain gating. |
| 15 (EN) | DC/DC enable input | CMOS-compatible active-high control (VIH ≥ 1.0 V); enables/disables buck converter; tri-states SW when disabled. |
| 16 (EN2) | LDO2 enable input | CMOS-compatible active-high control (VIH ≥ 1.0 V); enables/disables LDO2 independently for I/O rail control. |
Key Features
| Feature | Design Value |
|---|---|
| Triple-output power management | Single-chip integration of 2 MHz 600 mA DC/DC + dual 300 mA LDOs eliminates discrete PMIC complexity and reduces BOM count by ≥3 components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-output power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC2810-4GSYML-TR | Same package and architecture; LDO1 = 1.2 V, LDO2 = 3.3 V, DC/DC = 1.2 V - identical output configuration to MIC2810-4MSYML-TR. | No functional difference; both support identical voltage setpoints and timing specs - interchangeable where 1.2 V/3.3 V/1.2 V rail assignment matches. | Select MIC2810-4GSYML-TR only if cross-reference documentation explicitly confirms identical marking and test binning; verify CSET/POR behavior matches in target firmware. |
| TPS65023BRSAT | Three-output PMIC (2 buck + 1 LDO); 600 mA/600 mA/260 mA; no LOWQ mode; higher IQ (80 µA typical); fixed 1.2 V/1.5 V/3.3 V outputs. | Lacks ultra-low-noise light-load mode; POR not programmable; no backup-power-safe open-drain POR - unsuitable for RF-critical or backup-domain applications. | Choose TPS65023BRSAT only for cost-sensitive non-RF applications where 80 µA IQ and fixed 1.5 V LDO2 are acceptable; requires layout revision due to different pinout and thermal pad. |
Compared with MIC2810-4MSYML-TR, MIC2810-4GSYML-TR offers identical electrical and mechanical compatibility, whereas TPS65023BRSAT trades LOWQ noise performance and POR flexibility for broader vendor support but requires revalidation of sequencing and noise margins.

FAQ
What output voltages does the MIC2810-4MSYML-TR provide?
The MIC2810-4MSYML-TR provides three fixed output voltages: 1.2 V from the DC/DC converter, 1.2 V from LDO1, and 3.3 V from LDO2 - as confirmed by Microchip's Product Identification System for the "4MS" suffix. These values are factory-trimmed and do not require external feedback resistors.
How does the LOWQ mode affect the DC/DC output in MIC2810-4MSYML-TR?
In LOWQ mode (LOWQ pin pulled low), the MIC2810-4MSYML-TR disables the SW node and routes DC/DC regulation through the LDO pin, delivering 1.2 V with ≤53 µVRMS noise and ≤30 µA total IQ. Output current is limited to 60 mA, and LDO1/LDO2 loads are capped at <50 mA each.
Can the MIC2810-4MSYML-TR POR output interface directly with a backup power domain?
Yes - the MIC2810-4MSYML-TR POR pin has no internal clamping diodes to VIN, enabling safe open-drain connection to backup-supply rails (e.g., supercapacitor or coin cell). This prevents parasitic leakage and allows reliable reset assertion even when main power is removed.
What is the recommended capacitor value for setting a 500 µs POR delay on MIC2810-4MSYML-TR?
Per Equation 3-1 in the datasheet, the CSET pin current source is 1.25 µA, so a 500 µs POR delay requires a 500 pF capacitor from CSET to SGND. Values must avoid grounding CSET, and X7R ceramics are recommended for temperature stability.
Does MIC2810-4MSYML-TR support independent enable control for all three regulators?
Yes - MIC2810-4MSYML-TR provides three dedicated CMOS-compatible enable inputs: EN (DC/DC), EN1 (LDO1), and EN2 (LDO2), each requiring VIH ≥ 1.0 V for activation. All can be controlled independently to implement dynamic power domain gating without affecting other outputs.
