Product details
Overview
MIC2606YML-TR from Microchip Technology is a 2 MHz, 0.5A PWM boost switching regulator with integrated 40V bipolar switch and Schottky diode in an 8-lead 2 mm × 2 mm TDFN package. It operates from 4.5V to 20V input, delivers adjustable output up to 40V, and features programmable soft-start, UVLO, overvoltage and overtemperature protection - used in TFT-LCD bias supplies and broadband communications power stages.
For engineers reviewing the MIC2606YML-TR datasheet, MIC2606YML-TR pinout, MIC2606YML-TR application, or MIC2606YML-TR equivalent, this page delivers verified technical context, exact pin functions, real-world application cards, and two validated alternative parts for design-in decisions under tight board space and high-frequency EMI constraints.
Technical Context
The MIC2606YML-TR implements constant-frequency current-mode PWM control at 2 MHz (typical), enabling compact external components including ≤10 μH inductors and ceramic output capacitors. Its internal 0.5A bipolar switch and integrated Schottky diode eliminate external power devices while supporting up to 40V output voltage regulation.
It uses internal compensation with a 1.25V feedback reference, slope-compensated current sensing, and a dedicated soft-start pin (SS) for monotonic output ramp-up. Protection includes output overvoltage shutdown (15% above setpoint), thermal shutdown at 150°C with 10°C hysteresis, and <10 μA shutdown current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 2 MHz typical - enables use of small inductors & low-profile ceramics; reduces EMI fundamental frequency spacing. |
| Input Voltage Range | 4.5V to 20V - supports wide-input industrial and telecom rails without pre-regulation. |
| Output Voltage Range | Adjustable up to 40V - set via external resistor divider; suitable for LCD bias, DSL line drivers, and local boost rails. |
| Switch Current Limit | 0.5A minimum - defines maximum load capability and inductor peak-current sizing. |
| Feedback Reference | 1.25V ±2% - determines output accuracy; sets VOUT = 1.25 × (1 + R1/R2) with R2 ≤ 1 kΩ. |
| Max Duty Cycle | 80% - constrains minimum VIN-to-VOUT ratio; requires VIN ≥ VOUT × (1 − 0.8) for stable operation. |
| Shutdown Current | <0.1 μA typical - enables ultra-low-power system sleep modes without leakage concerns. |
| Junction Temp Range | −40°C to +125°C - qualified for automotive cabin, industrial control, and outdoor broadband equipment. |
Pinout & Package
Package: 8-lead 2 mm × 2 mm TDFN with exposed thermal pad (EPAD). RoHS-compliant, leadless, and optimized for high thermal conductivity on PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Output cathode node | Connects to output capacitor; carries full output current through internal Schottky diode. |
| VIN | Main input supply | 4.5–20V source; requires 1 μF ceramic bypass close to PGND for high-frequency stability. |
| VDD | Internal regulated supply | 5.8V internal rail; must tie to VIN when VIN ≤ 7V; bypass with 0.1 μF ceramic. |
| EN | Enable logic input | Active-high (≥1.5V); pulls device into <0.1 μA shutdown state when low; tri-states SW/VOUT. |
| SS | Soft-start control | Capacitor-to-ground sets output ramp time; 0.1 μF yields standard monotonic startup. |
| FB | Feedback voltage input | Senses output via resistor divider; compares to 1.25V reference to regulate VOUT. |
| SW | Switch node | Collector of internal bipolar transistor; connects to inductor; high dV/dt node requiring careful routing. |
| PGND | Power ground return | High-current return path for switch and Schottky; must be low-inductance, separate from analog ground. |
| EPAD | Thermal pad | Internally connected to PGND; soldered to PCB thermal plane for θJA = 90°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Schottky diode | Eliminates external diode; reduces BOM count and layout area; forward drop ≤850 mV @ 150 mA. |
| 2 MHz fixed-frequency PWM | Enables sub-2 mm inductors and <10 μF ceramic output caps; lowers input/output ripple vs. lower-frequency boosters. |
| Programmable soft-start | Prevents inrush current and output overshoot via external SS capacitor; avoids system brownouts during power-up. |
| Output overvoltage protection | Shuts down SW if VOUT exceeds programmed value by >15%; protects downstream circuitry during transients or feedback faults. |
| Stable with ceramic capacitors | No ESR requirement; supports X5R/X7R MLCCs only - simplifies filtering, improves reliability, and reduces footprint. |
| −40°C to +125°C operation | Qualified across full junction range; no derating needed for industrial ambient or automotive under-hood environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4312GJ-AEC1-P | 3.5A, 2.5 MHz, 36V output; AEC-Q100 Grade 1; requires external diode; larger 10-pin 3×3mm QFN. | Automotive infotainment displays needing higher current and AEC qualification; not drop-in due to pinout and external diode. | Select when >0.5A output or automotive qualification is required; re-layout needed. |
| TPS61088RHLR | 6A, 2.5 MHz, 22V output; integrated MOSFETs (no diode); 16-pin 3×3mm QFN; no OVP latch-off. | Higher-power portable electronics (e.g., tablet backlight drivers); lacks output overvoltage latch-off protection. | Choose for >0.5A loads and higher efficiency; verify OVP requirements match system safety architecture. |
Compared with MPQ4312GJ-AEC1-P and TPS61088RHLR, the MIC2606YML-TR offers the smallest footprint (2×2mm), integrated Schottky diode, and guaranteed OVP latch-off - making it optimal for space-constrained, medium-current bias supplies where reliability and simplicity outweigh raw current headroom.

FAQ
What is the maximum output voltage achievable with the MIC2606YML-TR?
The MIC2606YML-TR supports adjustable output voltages up to 40V, set by an external resistor divider on the FB pin. The internal 40V-rated switch and integrated Schottky diode enable safe operation at this limit. Output accuracy depends on feedback resistor tolerance and the 1.25V ±2% reference; for precise 32V outputs, use 1% resistors and confirm stability per Figure 2-8 efficiency curves in the datasheet.
Does the MIC2606YML-TR require an external Schottky diode?
No, the MIC2606YML-TR integrates a Schottky diode internally - its VOUT pin serves as the cathode connection. This eliminates the need for an external diode, reducing BOM count, PCB area, and potential layout errors. The diode's forward drop is ≤850 mV at 150 mA, and leakage is ≤4 μA at 30V reverse bias, as specified in the Electrical Characteristics table.
How does the MIC2606YML-TR handle overvoltage conditions?
The MIC2606YML-TR includes output overvoltage protection (OVP) that triggers when VOUT exceeds the programmed value by >15%. Upon detection, the internal switch (SW) shuts off and remains latched off until EN is cycled. This protects downstream components during feedback faults, load disconnection, or line transients - a key differentiator versus boost regulators without OVP latch-off.
What is the recommended inductor value for the MIC2606YML-TR?
Microchip recommends a 10 μH inductor for most MIC2606YML-TR applications, balancing efficiency, size, cost, and stability. Larger values reduce peak current ripple but increase DCR losses and require larger output capacitance to maintain loop stability due to right-half-plane zero effects. Inductor saturation current must exceed 0.8A (switch current limit), and core material should support 2 MHz operation (e.g., shielded ferrite or metal alloy).
Can the MIC2606YML-TR operate with input voltage below 5V?
No - the MIC2606YML-TR has a minimum input voltage of 4.5V per Absolute Maximum Ratings and Operating Ratings tables. Operation below 4.5V risks UVLO activation (VULVO = 1.8–2.4V on VDD) and unstable regulation. When VIN ≤ 7V, the VDD pin must be tied directly to VIN per datasheet Note 2; failure to do so may cause control circuit malfunction or premature shutdown.
