Product details
Overview
MIC23153YMT-TR from Microchip Technology is a 4 MHz synchronous buck DC-DC regulator delivering up to 2A output current with HyperLight Load® mode, Power Good (PG) indicator, and programmable soft-start. It operates from 2.7V–5.5V input, supports adjustable output (0.62V–3.6V), achieves 93% peak efficiency, and targets processor core rail supply in space-constrained portable electronics.
For engineers reviewing the MIC23153YMT-TR datasheet, MIC23153YMT-TR pinout, MIC23153YMT-TR application, or MIC23153YMT-TR equivalent, key selection criteria include its 2.5 mm × 2.5 mm TDFN package, ultra-fast transient response, 22 µA quiescent current, 4 MHz PWM operation, and compatibility with 0.47 µH inductors and 2.2 µF output capacitors.
Technical Context
The MIC23153YMT-TR implements a proprietary HyperLight Load® control architecture combining minimum on/off time PFM for light loads and fixed-frequency 4 MHz PWM in continuous conduction mode. It integrates PMOS and NMOS power switches with typical RDS(ON) of 0.2 Ω (high-side) and 0.19 Ω (low-side), enabling high efficiency across 1 mA to 2A load range.
Its feedback loop uses an internal 0.62 V reference and supports external resistor divider configuration via FB pin. The device features undervoltage lockout (2.55 V typ), thermal shutdown at 160°C, and open-drain PG output with 92% rising threshold and 68 µs delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Output Voltage Range | Adjustable 0.62 V to 3.6 V - Set via external FB resistor divider; enables precise core voltage tuning for SoCs/FPGAs. |
| Max Output Current | 2 A - Sustains full load in continuous conduction mode with proper thermal layout and 0.47–2.2 µH inductor. |
| Switching Frequency | 4 MHz - Enables use of sub-1 µH inductors and compact ceramic capacitors while minimizing audible noise. |
| Quiescent Current | 22 µA - Minimizes standby power loss in battery-powered devices during sleep or idle states. |
| Efficiency (Peak) | 93% - Achieved at medium-to-heavy loads in CCM; reduces thermal stress and extends battery life. |

Pinout & Package
Package: 10-pin 2.5 mm × 2.5 mm × 0.6 mm Thin DFN (TDFN) with exposed thermal pad; RoHS-compliant, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch Node | Internal PMOS/NMOS drain connection; routes high-frequency switching current to external inductor - requires short, low-inductance PCB trace. |
| EN | Enable Input | Active-high logic control (0.9 V typ threshold); pulls device into 0.01 µA shutdown state when low - must not float. |
| SNS | Output Voltage Sense | Direct connection to VOUT near output capacitor; provides precision regulation feedback independent of FB path. |
| NC | No Connect | Pin 4 in fixed-output variant only; unconnected internally - leave unpopulated or unconnected on PCB. |
| FB | Feedback Input | Connects to resistor divider from VOUT to GND; sets output voltage using internal 0.62 V reference - used only in adjustable configuration. |
| PG | Power Good Output | Open-drain signal indicating VOUT ≥ 92% nominal; requires external pull-up (≥5 kΩ) to VOUT or system rail. |
| SS | Soft-Start Control | Capacitor-to-ground node (min 100 pF); programs output ramp time (~320 µs with 470 pF) to limit inrush current. |
| AGND | Analog Ground | Reference ground for control circuitry; must be star-connected to central ground point, separate from PGND loop. |
| VIN | Input Supply | Dual-pin (8 & 9) for high-current input path; requires local 2.2 µF+ ceramic bypass capacitor close to pins and PGND. |
| PGND | Power Ground | High-current return path for MOSFETs and inductor; must be low-impedance, thermally coupled to exposed pad. |

FAQ
What output voltage range does the MIC23153YMT-TR support?
The MIC23153YMT-TR supports an adjustable output voltage range from 0.62 V to 3.6 V, set via an external resistor divider connected to the FB pin and referenced to its internal 0.62 V feedback voltage. This flexibility allows precise core voltage tuning for diverse SoCs and FPGAs without requiring multiple fixed-output variants. The MIC23153YMT-TR does not support fixed-output configurations - that functionality is reserved for part numbers like MIC23153-GYMT-TR.
How does HyperLight Load® mode improve efficiency in the MIC23153YMT-TR?
HyperLight Load® mode enables the MIC23153YMT-TR to achieve 85% typical efficiency at 1 mA by switching to pulse-frequency modulation (PFM) with minimum on/off timing control, reducing gate drive and switching losses. Unlike conventional buck regulators that drop sharply below 10% load, the MIC23153YMT-TR sustains high efficiency across the entire 1 mA–2 A range while preserving ultra-fast transient response - a key advantage for burst-mode processors.
What is the recommended inductor value for the MIC23153YMT-TR?
Microchip specifies a recommended inductor range of 0.47 µH to 2.2 µH for the MIC23153YMT-TR. A 0.47 µH inductor optimizes transient response for dynamic loads, while a 2.2 µH inductor minimizes output ripple in continuous conduction mode. The MIC23153YMT-TR is designed to remain stable with either value when paired with a 4.7 µF X5R/X7R ceramic output capacitor - enabling trade-offs between size, ripple, and response speed.
Does the MIC23153YMT-TR include built-in protection features?
Yes, the MIC23153YMT-TR integrates thermal shutdown (triggering at 160°C with 20°C hysteresis), cycle-by-cycle current limiting (3.3 A typical), undervoltage lockout (2.55 V turn-on threshold), and short-circuit protection. These features operate autonomously without external components, ensuring robust operation in portable and industrial environments where input transients or thermal overload may occur. The MIC23153YMT-TR also features 0.01 µA shutdown current for maximum battery preservation.
What package type and dimensions does the MIC23153YMT-TR use?
The MIC23153YMT-TR uses a 10-pin 2.5 mm × 2.5 mm × 0.6 mm Thin DFN (TDFN) package with an exposed thermal pad. Its compact footprint and low profile (<1 mm total solution height) enable integration into ultra-thin portable electronics such as SSD modules and mobile handsets. The package is Pb-free, RoHS-compliant, and rated for –40°C to +125°C junction temperature - matching the operational limits of the MIC23153YMT-TR silicon.
