Product details
Overview
MIC2290YML-TR from Microchip Technology is a 1.2 MHz PWM boost switching regulator with internal Schottky diode, 2.5V–10V input range, adjustable output up to 34V, 750 mA switch current, and stable operation with ceramic capacitors - used in TFT LCD bias supplies and organic EL power management.
For engineers reviewing the MIC2290YML-TR datasheet, MIC2290YML-TR pinout, MIC2290YML-TR application, or MIC2290YML-TR equivalent, this page delivers verified functional specifications, validated DFN-8 pin roles, confirmed thermal and protection features, and real-world design constraints for battery-powered and high-density DC-DC conversion.
Technical Context
The MIC2290YML-TR implements constant-frequency current-mode PWM control using an internal 0.5A bipolar transistor and 1.24V reference amplifier. Its oscillator runs at 1.2 MHz ±15%, enabling compact external components while maintaining low output ripple and predictable transient response.
It integrates undervoltage lockout (2.1 V typical), overvoltage protection (32 V nominal), overtemperature shutdown (150°C), and internal Schottky diode (0.8 V forward drop at 150 mA) - all within a thermally enhanced 2 mm × 2 mm DFN package with exposed pad for thermal dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 1.2 MHz typical; enables use of small 10 µH inductors and 10 µF ceramic output capacitors without stability compromise. |
| Input Voltage Range | 2.5 V to 10 V; supports direct operation from 1–2-cell Li-ion, 3–4-cell alkaline/NiMH, and fixed 3.3 V/5 V rails. |
| Output Voltage Range | Adjustable up to 34 V via FB resistor divider; internal 34 V OVP clamp protects downstream circuitry. |
| Switch Current Limit | 750 mA typical; limits peak inductor current to sustain reliable operation under load transients and short-circuit conditions. |
| Feedback Reference | 1.24 V ±1% at 25°C; sets output voltage accuracy and enables precise regulation across –40°C to +125°C junction range. |
| Shutdown Current | <1 µA typical; minimizes battery drain in portable systems during standby or disable states. |
| Thermal Resistance | θJA = 93°C/W; requires proper PCB copper area under EP pad to maintain ≤125°C junction temperature at full load. |
Pinout & Package
Package: 2 mm × 2 mm, 8-pin DFN (ML), exposed thermal pad (EP/GND), RoHS-compliant, –40°C to +125°C junction temperature rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output node | Connects to feedback divider; includes internal 34 V overvoltage clamp to prevent runaway during FB open-circuit faults. |
| 2 (VIN) | Main power input | Accepts 2.5–10 V supply; must be decoupled with ≥1 µF ceramic capacitor placed near pin. |
| 3 (EN) | Enable control input | Logic-high (>1.5 V) enables regulation; logic-low (<0.4 V) disables with <1 µA quiescent draw; must not float. |
| 4 (AGND) | Analog ground reference | Reference for FB, error amplifier, and internal bias circuits; separate from PGND to minimize noise coupling. |
| 5 (NC) | No-connect terminal | No internal connection; leave unconnected and unbonded on PCB layout. |
| 6 (FB) | Voltage feedback input | Senses output via resistor divider; 1.24 V reference sets regulation point; input current ≤450 nA minimizes divider error. |
| 7 (SW) | Internal switch collector | Connects to inductor and Schottky cathode; carries pulsed 750 mA current; requires low-inductance routing. |
| 8 (PGND) | Power ground return | Return path for switch current and Schottky anode; tie to AGND only at single point near IC. |
| EP (GND) | Exposed thermal pad | Internally connected to PGND; must be soldered to large PCB copper pour for thermal and electrical performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Schottky diode | Eliminates external diode, reducing BOM count and board area; 0.8 V forward drop at 150 mA improves light-load efficiency. |
| Ceramic-capacitor stability | Operates stably with X5R/X7R ceramics (e.g., 10 µF output cap), avoiding costly tantalum or electrolytic alternatives. |
| Line/load regulation | <0.1% line and <0.2% load regulation ensures consistent output across input and load variations in precision bias applications. |
| Protection suite | Includes UVLO (2.1 V), OVP (32 V), and thermal shutdown (150°C) - critical for unattended operation in display and sensor modules. |
| High power density | Delivers up to 34 V at 750 mA from a 4 mm² footprint, enabling compact designs for space-constrained OLED and CCD bias supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | Higher 5-A switch current, wider 2.7–12-V input, but larger 3 mm × 3 mm QFN package and no integrated Schottky. | Better suited for high-current loads (>500 mA); requires external diode and larger layout area. | Select when >750 mA output current or >10 V input is required; avoid if board space or BOM count is constrained. |
| MAX17222ETA+ | Lower 400 mA switch current, 0.7–5.5 V input, 1.2-MHz operation, integrated Schottky, but only 20 V max output. | Ideal for sub-20 V, ultra-low-power applications (e.g., wearables); limited headroom for 24–34 V bias rails. | Select for compact, low-IQ (<1 µA) designs below 20 V; not suitable for 34 V OLED or CCD applications. |
Compared with TPS61088RHLR and MAX17222ETA+, the MIC2290YML-TR uniquely balances 34 V output capability, integrated Schottky, and 2 mm × 2 mm footprint - making it optimal for space-limited, medium-current display and imaging bias supplies where external diode omission and thermal efficiency are critical.

FAQ
What is the maximum output voltage supported by the MIC2290YML-TR?
The MIC2290YML-TR supports adjustable output voltage up to 34 V, set by an external resistor divider on the FB pin. Its internal overvoltage protection activates at 32 V nominal to safeguard downstream circuitry during feedback faults. This makes the MIC2290YML-TR suitable for high-voltage bias rails in OLED and CCD applications where precise regulation and fault resilience are required.
Does the MIC2290YML-TR require an external Schottky diode?
No, the MIC2290YML-TR integrates a Schottky diode with 0.8 V forward drop at 150 mA, eliminating the need for an external diode. This reduces BOM count, saves PCB area, and improves reliability in compact designs such as handheld displays and imaging modules where the MIC2290YML-TR is commonly deployed.
What is the recommended inductor value for the MIC2290YML-TR in a typical 5 V to 12 V boost application?
Microchip recommends a 10 µH inductor for most MIC2290YML-TR applications, including 5 V to 12 V conversion at up to 110 mA. This value balances efficiency, stability, and size - as confirmed in Figure 6-6 of the datasheet. Inductor saturation current should exceed 750 mA to accommodate peak switch current without core saturation.
How does the MIC2290YML-TR handle thermal overload conditions?
The MIC2290YML-TR includes overtemperature protection that shuts down the internal switch at 150°C junction temperature, with 10°C hysteresis. Once cooled, it automatically resumes operation. This behavior prevents permanent damage during sustained overload or poor heatsinking - a key reliability feature in sealed enclosures where the MIC2290YML-TR powers display bias rails.
Can the MIC2290YML-TR operate from a single-cell Li-ion battery?
Yes, the MIC2290YML-TR operates from 2.5 V to 10 V input, fully supporting single-cell Li-ion batteries (3.0–4.2 V). Its 2.1 V undervoltage lockout prevents erratic startup at end-of-discharge, and its 1.2 MHz switching allows efficient 9 V or 12 V output even at 3.3 V input - as demonstrated in Figures 6-2 through 6-4 of the MIC2290YML-TR datasheet.
