Product details
Overview
MIC2295YML-TR from Micrel is a high-power-density 1.2 MHz PWM boost regulator with an integrated 34 V / 1.2 A bipolar switch, designed for space-constrained DC/DC conversion in portable electronics. It delivers up to 34 V output from 2.5–10 V input, features internal compensation, and operates in a thermally efficient 2 mm × 2 mm MLF-8L package with output over-voltage protection (OVP).
For engineers reviewing the MIC2295YML-TR datasheet, MIC2295YML-TR pinout, MIC2295YML-TR application, or MIC2295YML-TR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, OVP-enabled use cases, and two confirmed alternative parts with documented functional distinctions.
Technical Context
The MIC2295YML-TR implements constant-frequency current-mode PWM control using a 1.2 MHz oscillator, slope-compensated ramp generator, and gm error amplifier referenced to 1.24 V. Its bipolar switch enables high peak-current capability without external MOSFET drive complexity.
It integrates OVP functionality via dedicated OVP pin (pin 1), clamping output to ≤34 V during feedback loss or open-load faults-exclusive to the MLF-8L variant. Thermal shutdown triggers at 150°C with 10°C hysteresis, and UVLO activates below 2.1 V typical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | 1.5 A MOSFET switch, 2.7–12 V input, no integrated OVP, requires external compensation. | Lacks hardware OVP; suited for cost-sensitive consumer apps where fault protection is handled system-level. | Choose when higher output current (1.5 A) is needed and OVP can be implemented externally. |
| MAX17062ETA+ | 1.2 A switch, 2.6–5.5 V input only, includes soft-start and power-good, no OVP pin. | Input range too narrow for 10 V applications; lacks OVP; better for fixed 3.3 V→5 V/12 V conversion. | Prefer when input is strictly ≤5.5 V and power-good signaling is required; not suitable for 10 V input or OVP-critical designs. |
Compared with TPS61088RHLR and MAX17062ETA+, the MIC2295YML-TR uniquely combines OVP pin control, 10 V input support, and bipolar switch ruggedness-making it the only choice for Li-ion-powered OLED displays requiring fail-safe voltage clamping without added components.

FAQ
What is the maximum output voltage supported by the MIC2295YML-TR?
The MIC2295YML-TR supports adjustable output voltages up to 34 V, enforced by its internal output over-voltage protection circuit. This limit is hardware-defined and active only in the MLF-8L package variant (e.g., MIC2295YML-TR), where the OVP pin (pin 1) is connected to VOUT. The 34 V clamp prevents damage to downstream components during feedback failure or open-load conditions.
Does the MIC2295YML-TR require external compensation components?
No, the MIC2295YML-TR features fully internal compensation, eliminating the need for external RC networks on the FB pin. This simplifies PCB layout, reduces bill-of-materials count, and ensures consistent loop stability across temperature and load variations-verified from −40°C to +125°C junction temperature.
Can the MIC2295YML-TR operate from a 10 V input source?
Yes, the MIC2295YML-TR supports an input voltage range of 2.5 V to 10 V, making it compatible with 10 V sources such as regulated industrial rails or charged supercapacitors. At VIN = 10 V, the maximum usable output voltage is limited by the 85% max duty cycle, yielding VOUT ≤ 66.7 V theoretically-but OVP caps practical output at 34 V.
How does the OVP function work on the MIC2295YML-TR?
The OVP function on the MIC2295YML-TR monitors output voltage via the dedicated OVP pin (pin 1). When tied to VOUT, it triggers internal shutdown if voltage exceeds 34 V (typical), clamping further rise. If OVP is not required, pin 1 must be tied to ground. This feature is exclusive to the MLF-8L package and absent in SOT-23 variants like MIC2295YD5.
What is the thermal performance of the MIC2295YML-TR in its MLF-8L package?
The MIC2295YML-TR in the 2 mm × 2 mm MLF-8L package has a junction-to-ambient thermal resistance (θJA) of 93°C/W when mounted on a 1 cm² copper pad. With its −40°C to +125°C junction rating and thermal shutdown at 150°C, it sustains continuous 1.2 A switch current at room temperature and derates gracefully under high ambient or high-duty-cycle conditions.
