Product details
Overview
MIC2296YML-TR from Micrel is a 600kHz PWM DC/DC boost regulator with internal 34V/1.2A bipolar switch, housed in a 2mm × 2mm 8-pin MLF® package. It delivers up to 15V/100mA or 5V/400mA from single-cell Li-ion (3V–4.2V) input, features output over-voltage protection (OVP), and operates across –40°C to +125°C junction temperature.
For engineers reviewing the MIC2296YML-TR datasheet, MIC2296YML-TR pinout, MIC2296YML-TR application, or MIC2296YML-TR equivalent, this page provides verified functional context, validated pin roles, confirmed OVP capability, thermal shutdown behavior, and real-world design constraints for high-density portable power conversion.
Technical Context
The MIC2296YML-TR implements constant-frequency current-mode PWM control using an internal 600kHz oscillator, slope-compensated ramp generator, and gm error amplifier referenced to 1.24V. Its bipolar switch architecture enables robust 1.2A peak current handling with low saturation voltage (250mV at 0.5A).
It integrates internal compensation for stable operation with small ceramic capacitors, supports adjustable output up to 34V via external feedback resistors, and includes dedicated OVP functionality tied to the OVP pin-active only in the MLF-8L package variant (e.g., MIC2296YML-TR).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Current Limit | 1.2A typical - sets maximum inductor peak current and load capability without external current sensing. |
| Oscillator Frequency | 600kHz ±12.5% - enables compact 4.7µH–10µH inductors and low-profile ceramic output capacitors. |
| Feedback Reference Voltage | 1.24V ±1% - defines output regulation accuracy; VOUT = 1.24V × (1 + R1/R2). |
| Input Voltage Range | 2.5V to 10V - supports single-cell Li-ion (3V–4.2V), 3.3V, and 5V rail boosting. |
| Output Over-Voltage Threshold | 32V typical (30–34V range) - clamps output during FB open-circuit or short-to-ground faults. |
| Shutdown Current | <1µA - minimizes battery drain in standby mode for portable applications. |
| Junction Temperature Range | –40°C to +125°C - qualified for automotive cabin, industrial, and harsh-environment use. |
Pinout & Package
Package: 2mm × 2mm, 8-pin leadless MLF® (MicroLeadFrame) with exposed thermal pad (EP). RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OVP | Over-Voltage Protection Input | Connect to VOUT to enable 34V clamping; tie to GND to disable OVP function. |
| VIN | Power Input | Accepts 2.5V–10V supply; requires ≥1µF ceramic capacitor placed near pin. |
| EN | Enable Control | Logic-high (>1.5V) enables regulation; logic-low (<0.4V) disables switch and reduces quiescent current to <1µA. |
| AGND | Analog Ground | Reference ground for FB and OVP; separate from PGND to minimize noise coupling into feedback path. |
| NC | No Connect | Internally unconnected; must be left floating or grounded per layout best practice. |
| FB | Feedback Sense | Monitors resistor divider output; regulates VOUT to 1.24V at this node. |
| SW | Switch Node | Internal bipolar collector node; connects to inductor and Schottky diode anode; swings from VIN to ~34V. |
| PGND | Power Ground | High-current return path for switch and inductor; must be tied to AGND at single point near IC. |
| EP | Exposed Pad | Thermal and electrical ground; soldered to PCB copper pour for θJA = 93°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Output Over-Voltage Protection | Hardware-clamped 34V limit activated by OVP pin connection - prevents SW node overstress during FB fault conditions. |
| Internal Compensation | Eliminates need for external compensation network - simplifies layout and ensures stability with 4.7µF–10µF X5R/X7R ceramic output capacitors. |
| Low Shutdown Current | <1µA shutdown leakage - extends battery life in always-on portable systems requiring periodic wake-up cycles. |
| High Switch Current Density | 1.2A integrated bipolar switch in 4mm² footprint - enables >400mA 5V output from 3.6V input without external MOSFET. |
| Thermal Shutdown | 150°C trip with 10°C hysteresis - protects die during sustained overload or poor heatsinking without latch-up. |
Applications
| Organic EL Power Supply | TFT-LCD Bias Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | 12V max input; 5.5A switch; 2.5MHz operation; no OVP pin; uses external compensation. | Higher current, higher frequency - suited for ultra-compact 1A+ designs but requires careful loop tuning and adds BOM cost. | Select when >1A output or <1MHz EMI filtering is required; not drop-in due to different pinout, compensation, and lack of hardware OVP. |
| MAX17062ETA+ | 2.7V–5.5V input; 1.2A switch; 1.2MHz; integrated Schottky; no OVP; -40°C to +85°C rating. | Narrower input range and temp grade - fits consumer-grade 3.3V-to-5V boost but unsuitable for automotive or wide-temp industrial use. | Choose for cost-sensitive, space-constrained 3.3V systems where extended temperature and OVP are not critical. |
Compared with TPS61088RHLR and MAX17062ETA+, the MIC2296YML-TR uniquely combines 34V OVP clamping, –40°C to +125°C operation, and internal compensation in a 2mm × 2mm MLF package - making it optimal for ruggedized, fault-tolerant portable power where board area and reliability outweigh raw current or frequency specs.

FAQ
What is the function of the OVP pin on the MIC2296YML-TR?
The OVP pin on the MIC2296YML-TR enables hardware-based output over-voltage protection. When connected to VOUT, it clamps the regulated output to ≤34V during feedback loop faults (e.g., FB resistor open or shorted to ground). If OVP is not needed, tie the pin to ground. This feature is exclusive to the MLF-8L package variants like MIC2296YML-TR and is absent in SOT-23 versions.
Does the MIC2296YML-TR require external compensation components?
No, the MIC2296YML-TR features fully internal compensation optimized for stability with standard 4.7µF–10µF X5R/X7R ceramic output capacitors. No external RC networks or type-II/type-III compensators are needed - reducing BOM count, layout complexity, and tuning effort while maintaining <1% load regulation across –40°C to +125°C.
What is the maximum output voltage achievable with the MIC2296YML-TR?
The MIC2296YML-TR supports adjustable output voltages up to 34V, limited by its internal switch breakdown rating and OVP threshold. Output is set via external feedback resistors using VOUT = 1.24V × (1 + R1/R2). For reliable operation, ensure duty cycle remains below 90% - e.g., 3.6V input can safely generate 15V (D ≈ 76%) but not 30V (D ≈ 88%) under full load.
Can the MIC2296YML-TR operate from a single-cell Li-ion battery?
Yes, the MIC2296YML-TR is explicitly designed for single-cell Li-ion inputs (3.0V–4.2V). Its 2.5V–10V input range, <1µA shutdown current, and 600kHz fixed-frequency operation allow efficient 5V/400mA or 12V/120mA conversion across the full battery discharge curve without brownout or instability.
How does thermal performance differ between the MLF and SOT-23 packages of the MIC2296?
The MIC2296YML-TR's 2mm × 2mm MLF-8L package has θJA = 93°C/W with proper PCB copper pour on the exposed pad, enabling higher continuous output current before thermal shutdown. In contrast, the Thin SOT-23-5 (e.g., MIC2296YD5) lacks an exposed thermal pad and exhibits significantly higher thermal resistance - limiting usable output power in sustained high-load conditions.
