Product details
Overview
MIC23153-GYMT-TR from Microchip Technology is a 4 MHz synchronous buck regulator delivering up to 2 A output current with fixed 1.8 V output, HyperLight Load® mode for ultra-fast transient response, Power Good (PG) indicator, and programmable soft-start. It operates from 2.7 V to 5.5 V input, achieves 93% peak efficiency, and targets core voltage regulation in space-constrained portable electronics.
For engineers reviewing the MIC23153-GYMT-TR datasheet, MIC23153-GYMT-TR pinout, MIC23153-GYMT-TR application, or MIC23153-GYMT-TR equivalent, this page provides verified technical context, package mapping, real-world design meaning of key specs, and validated alternative options for SSD, GPS, and wireless module power designs.
Technical Context
The MIC23153-GYMT-TR implements a proprietary HyperLight Load® control architecture combining minimum on/off time PFM at light loads (<120 mA) and fixed 4 MHz PWM in continuous conduction mode (CCM), enabling high efficiency across full load range. Its integrated PMOS/NMOS power stage features 0.2 Ω high-side and 0.19 Ω low-side RDS(ON), supporting operation down to 0.47 µH inductors and 2.2 µF output capacitors.
It integrates analog ground (AGND) and power ground (PGND) separation, open-drain PG output with 92% rising threshold and 68 µs delay, and a dedicated soft-start pin (SS) accepting ≥100 pF capacitor to control VOUT ramp time-critical for preventing overshoot during processor core startup sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion (3.0–4.2 V) and USB-powered systems without external LDO pre-regulation. |
| Output Voltage | Fixed 1.8 V ±2.5% - matches standard I/O or low-power logic rail requirements; no external feedback resistors needed. |
| Max Output Current | 2 A - sufficient for ARM Cortex-A/M series application processors and high-speed NAND flash in SSDs. |
| Switching Frequency | 4 MHz - enables use of sub-1 µH inductors and compact ceramic capacitors, reducing solution height to <1 mm. |
| Quiescent Current | 22 µA - extends battery life in always-on GPS or Wi-Fi modules during standby. |
| Efficiency (Peak) | 93% - minimizes thermal dissipation in sealed handheld enclosures; 85% maintained at 1 mA for ultra-low-power states. |
| Thermal Range | –40°C to +125°C junction - qualified for automotive infotainment and industrial portable equipment. |
Pinout & Package
Package: 10-pin 2.5 mm × 2.5 mm × 0.6 mm Thin DFN (TDFN), exposed thermal pad, RoHS-compliant, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch Node | High-frequency power switching node connecting to inductor; requires short, low-inductance routing to minimize EMI and ringing. |
| EN | Enable Input | Active-high logic control (0.9 V threshold); pulls device into 0.01 µA shutdown state when low-enables system-level power sequencing. |
| SNS | Output Voltage Sense | Direct connection to VOUT near output capacitor; provides precision feedback path for regulation accuracy and load transient stability. |
| NC | No Connect | Pin 4 (fixed version) is unconnected internally-must be left floating or grounded per layout best practice; not usable as spare I/O. |
| PG | Power Good Open-Drain | Asserts logic high (via external pull-up) when VOUT reaches ≥92% of 1.8 V; used for processor reset synchronization and system power validation. |
| SS | Soft-Start Timing | Capacitor-to-ground node (≥100 pF) controlling VOUT rise time (~320 µs with 470 pF); prevents inrush current and overshoot during cold boot. |
| AGND | Analog Ground Reference | Low-noise return for internal error amplifier and reference circuitry; must be star-connected separately from PGND to avoid noise coupling. |
| VIN | Main Input Supply | Dual-pin (8 & 9) configuration lowers impedance path for high di/dt currents; requires ≥2.2 µF ceramic bypass capacitor placed adjacent to pins. |
| PGND | Power Ground Return | High-current return path for MOSFET switching; must be routed with minimal loop area and tied to AGND at single point near IC. |
Key Features
| Feature | Design Value |
|---|---|
| HyperLight Load® Mode | Enables PFM operation below ~120 mA, sustaining 85% efficiency at 1 mA while delivering ultra-fast load transients (<10 µs recovery from 10 mA → 500 mA step). |
| Integrated Power MOSFETs | Eliminates need for external high-side/low-side switches; 0.2 Ω / 0.19 Ω RDS(ON) reduces conduction loss and simplifies BOM for compact DC/DC solutions. |
| Power Good (PG) Output | Open-drain signal with 68 µs delay and 7% hysteresis ensures reliable system power sequencing and fault detection before host processor release from reset. |
| 4 MHz Fixed-Frequency PWM | Allows use of 0.47 µH inductors and small 0603-size ceramic capacitors, achieving total solution size under 15 mm² and height <1 mm. |
| Thermal Shutdown Protection | Triggers at 160°C with 20°C hysteresis, preventing damage during sustained overload or poor PCB thermal design-critical for sealed portable devices. |

FAQ
What is the output voltage of the MIC23153-GYMT-TR?
The MIC23153-GYMT-TR has a fixed 1.8 V output voltage, confirmed by its part number suffix "G" per Microchip's Product Identification System. Output accuracy is ±2.5% over temperature and load, with a 0.62 V internal reference used in the feedback loop. This eliminates the need for external resistor dividers, simplifying layout and reducing BOM count compared to adjustable variants like MIC23153YMT-TR.
Does the MIC23153-GYMT-TR include Power Good (PG) functionality?
Yes, the MIC23153-GYMT-TR includes a dedicated open-drain Power Good (PG) output that asserts high when the output voltage reaches ≥92% of nominal 1.8 V, with 7% hysteresis and a 68 µs delay. This signal is essential for synchronizing processor reset release and validating power integrity in SSD and GPS applications-functionality explicitly documented in the DS20006489B datasheet Section 3.0 and Figure 2-34.
What package type and dimensions does the MIC23153-GYMT-TR use?
The MIC23153-GYMT-TR uses a 10-pin 2.5 mm × 2.5 mm × 0.6 mm Thin DFN (TDFN) package with an exposed thermal pad, as specified in DS20006489B-page 2 and Section 6.1. This package supports high thermal performance (θJA = 90°C/W) and enables ultra-compact PCB layouts-critical for mobile handsets and portable media players where board area is at a premium.
How does HyperLight Load® mode improve efficiency in the MIC23153-GYMT-TR?
HyperLight Load® mode enables pulse-frequency modulation (PFM) operation below ~120 mA, maintaining 85% efficiency at 1 mA while delivering ultra-fast transient response. Unlike conventional buck converters that drop sharply in light-load efficiency, the MIC23153-GYMT-TR sustains high conversion efficiency across the entire load range-directly enabling longer battery life in GPS trackers and SSDs during standby or low-activity states.
What is the recommended soft-start capacitor value for the MIC23153-GYMT-TR?
The MIC23153-GYMT-TR requires a minimum 100 pF capacitor from the SS pin to ground, with typical values around 470 pF yielding ~320 µs soft-start time. This capacitor controls the VOUT ramp rate to prevent overshoot and inrush current during startup-critical for protecting downstream logic in mobile handsets and Wi-Fi modules. The exact relationship is defined in Equation 4-1 of the DS20006489B datasheet.
