Product details
Overview
MIC2206-83YML-TR from Microchip Technology is a 2 MHz synchronous buck regulator with integrated MOSFETs and dual-mode operation (PWM/LDO), delivering up to 600 mA output current in PWM mode and 60 mA in LDO mode, with 18 µA quiescent current in LDO mode and 75 µVRMS output noise - deployed in USB peripherals and portable battery-powered systems.
For engineers reviewing the MIC2206-83YML-TR datasheet, MIC2206-83YML-TR pinout, MIC2206-83YML-TR application, or MIC2206-83YML-TR equivalent, key selection criteria include input voltage range (2.7–5.5 V), LOWQ mode control logic, 100% duty cycle capability for low-dropout operation, thermal shutdown at 160°C, and compatibility with 1 µF ceramic output capacitors.
Technical Context
The MIC2206-83YML-TR implements a constant-frequency 2 MHz PWM control architecture with anti-shoot-through protection and internal high-side P-channel and low-side N-channel MOSFETs. Its dual-mode operation is governed by the LOWQ pin: logic low enables ultra-low-noise LDO regulation (18 µA IQ, 60 mA IOUT), while logic high activates full PWM switching (600 mA IOUT, >95% efficiency).
It features internal error amplifiers, soft-start, UVLO with 100 mV hysteresis, and independent analog (AVIN/AGND) and power (VIN/PGND) supply paths to isolate noise-sensitive bias circuitry from high-current switching nodes - critical for maintaining PSRR >40 dB in LDO mode and stable regulation under transient load steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion, Li-poly, or regulated 3.3 V/5 V rails without external pre-regulation. |
| Output Current (PWM) | 600 mA - sufficient for powering core logic, RF transceivers, or small microcontrollers directly from battery. |
| Quiescent Current (LDO) | 18 µA typical - extends battery life in system sleep/standby by minimizing idle drain while maintaining clean 1.0 V output. |
| Switching Frequency | 2 MHz ±10% - enables use of compact 2.2 µH inductors and reduces EMI filtering burden in space-constrained portable designs. |
| Output Noise (LDO) | 75 µVRMS (10 Hz–100 kHz) - meets stringent analog/RF supply requirements without additional LDO post-regulation. |
| Max Duty Cycle | 100% - allows operation with minimal input-to-output differential (e.g., 1.0 V out from 1.1 V input), essential for low-VIN battery end-of-life conditions. |
| Thermal Shutdown | 160°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design without latch-up. |
| Package | VDFN-10 (3 mm × 3 mm × 0.9 mm) - exposes thermal pad (EP) for direct PCB copper connection, achieving θJA = 60°C/W. |
Pinout & Package
Packaged in a Pb-free 10-lead Very Thin Dual Flat No-Lead (VDFN-10ML) measuring 3 mm × 3 mm × 0.9 mm with exposed thermal pad (EP/GND), the MIC2206-83YML-TR requires separate AGND and PGND routing to minimize noise coupling between analog control and power switching sections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 AGND | Analog ground reference | Return path for FB, BIAS, and internal error amplifier - must be isolated from PGND to prevent switching noise injection into feedback loop. |
| 2 LDO | LDO output node | Connects directly to VOUT in LOWQ mode; becomes high-impedance in PWM mode - enables seamless handoff between regulation modes. |
| 3 BIAS | Analog bias supply input | Powered via internal 6 Ω resistor from AVIN; requires 0.1 µF local decoupling to stabilize reference and control circuitry. |
| 4 AVIN | Analog supply input | Provides power to LDO block and bias circuitry; must tie to VIN but routed separately to avoid coupling SW node noise. |
| 5 FB | Feedback input | Connects to internal resistive divider; 100 pF capacitor to VOUT improves phase margin and suppresses high-frequency oscillation. |
| 6 EN | Enable control input | Logic-low disables entire device (<5 µA shutdown current); no pull-up required - compatible with open-drain MCU GPIO. |
| 7 LOWQ | Mode select input | Logic-low forces LDO mode (18 µA IQ, 60 mA IOUT); logic-high enables PWM mode (600 mA IOUT, 2 MHz switching). |
| 8 VIN | Main power input | Supplies high-current MOSFET drivers and switches; requires ≥1 µF X5R/X7R ceramic capacitor placed adjacent to VIN–PGND. |
| 9 SW | Switch node output | Drives external inductor; high dV/dt demands short, wide trace routing away from sensitive analog nodes (FB, BIAS, AGND). |
| 10 PGND | Power ground return | Low-impedance return path for inductor current and MOSFET body diode conduction - forms tight loop with VIN and SW. |
| EP GND | Exposed thermal pad | Internally connected to PGND; must be soldered to large PCB copper pour for thermal dissipation and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Light-load LDO mode | Reduces quiescent current to 18 µA while maintaining regulated 1.0 V output - eliminates burst-mode ripple that disrupts RF/analog circuits. |
| Fully integrated MOSFETs | Eliminates need for external high-side P-channel and low-side N-channel switches - simplifies layout and reduces BOM count by two discrete components. |
| Stable with 1 µF ceramic output | Enables use of small, low-ESR/ESL capacitors without external compensation - cuts solution size and cost versus regulators requiring ≥10 µF output capacitance. |
| Ultra-fast transient response | Delivers sub-10 µs recovery from 50% load step (e.g., 0→300 mA) - maintains <1% VOUT deviation in processor wake-up events. |
| 100% duty cycle operation | Supports dropout as low as 100 mV at full load - sustains regulation during deep battery discharge when VIN approaches VOUT. |
| Micropower shutdown | Draws <0.1 µA when EN = low - suitable for always-on backup rails where leakage must be minimized over years of storage. |

FAQ
What output voltage does the MIC2206-83YML-TR deliver in PWM and LDO modes?
The MIC2206-83YML-TR delivers a fixed 1.0 V output in LDO mode (LOWQ = low) and a fixed 1.0 V output in PWM mode (LOWQ = high). Per Microchip's Product Identification System, the "83" suffix denotes "XXV PWM/XXV LDO", and confirmed fixed-output variants like MIC2206-1.8YML-TR specify "1.8V PWM/1.0V LDO"; thus MIC2206-83YML-TR provides 1.0 V in both modes. This is validated by the functional block diagram showing 1.0 V LDO output and absence of external feedback resistors in typical application schematics.
How does the MIC2206-83YML-TR achieve ultra-low noise in LDO mode?
The MIC2206-83YML-TR achieves 75 µVRMS output noise in LDO mode by disabling all switching circuitry - including the PWM controller, gate drivers, and power MOSFETs - and using a dedicated linear regulator block powered from AVIN. This eliminates switching artifacts entirely, unlike PFM or burst-mode regulators that generate low-frequency ripple. The LDO block uses internal compensation and is specified to operate with only a 1 µF ceramic output capacitor, ensuring stability without added filtering components.
Can the MIC2206-83YML-TR operate with a 1.0 V input voltage?
No, the MIC2206-83YML-TR cannot operate with a 1.0 V input voltage. Its absolute minimum input supply voltage is 2.7 V, and undervoltage lockout engages below 2.45 V (typical). While it supports 100% duty cycle for low-dropout operation, this applies only when VIN is within the 2.7–5.5 V operating range - for example, delivering 1.0 V output from a 1.1 V input is not possible. Operation below 2.7 V risks undefined behavior or shutdown.
What is the purpose of the AVIN and AGND pins on the MIC2206-83YML-TR?
The AVIN pin supplies power to the LDO block and internal bias circuitry through an internal 6 Ω resistor, while AGND serves as the dedicated analog ground reference for the feedback amplifier, error amplifier, and bias network. Both must be routed separately from VIN and PGND to prevent high-frequency switching noise from degrading regulation accuracy and PSRR. AVIN must connect to VIN externally but with careful layout to filter noise before reaching the analog section.
Does the MIC2206-83YML-TR require external compensation components?
No, the MIC2206-83YML-TR does not require external compensation components. It uses internal type III compensation optimized for 1–4.7 µF ceramic output capacitors and a 2.2 µH inductor, as confirmed in Section 5.2 of the datasheet. The 100 pF capacitor from FB to VOUT is a stability enhancement, not a compensation network - it improves phase margin without altering loop dynamics. External RC networks or feedforward capacitors are unnecessary and not recommended.
