Product details
Overview
MIC23030-GYMT-TR from Microchip Technology is a 1.8 V fixed-output, 400 mA synchronous buck regulator operating from 2.7 V to 5.5 V input, delivering up to 91% efficiency at full load and 83% at 1 mA, with 21 µA quiescent current and 8 MHz PWM switching in continuous mode - deployed in portable GPS modules and USB-powered devices.
For engineers reviewing the MIC23030-GYMT-TR datasheet, MIC23030-GYMT-TR pinout, MIC23030-GYMT-TR application, or MIC23030-GYMT-TR equivalent, this page delivers verified technical context, HyperLight Load® transient behavior, TDFN-6 package layout guidance, and validated alternative options for low-voltage, high-efficiency DC/DC conversion in space-constrained portable electronics.
Technical Context
The MIC23030-GYMT-TR implements a proprietary HyperLight Load® control architecture combining minimum on/off-time PFM at light loads and fixed-frequency 8 MHz PWM above ~120 mA (with 0.47 µH inductor), enabling ultra-fast load transients and sub-15 mVPP output ripple. Its integrated PMOS/NMOS power stage eliminates external diode losses and supports operation down to 1.8 V output with 0.65 Ω high-side RDS(ON).
Thermal protection triggers at 160°C with 20°C hysteresis, and undervoltage lockout activates below 2.45 V on VIN. The device uses separate AGND and PGND pins in its fixed-output variant to isolate analog bias paths from high-current switching return paths, improving noise immunity and regulation accuracy across –40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion, USB 5 V, and regulated 3.3 V rails without external LDO pre-regulation. |
| Output Voltage | Fixed 1.8 V ±2.5% - eliminates external feedback resistors and simplifies layout for core logic or I/O supply in portable SoC designs. |
| Max Output Current | 400 mA - sufficient for powering ARM Cortex-M cores, Wi-Fi baseband ICs, or FPGA I/O banks in compact form factors. |
| Switching Frequency | 8 MHz (PWM mode) - enables use of sub-1 mm height 0.47 µH inductors and small 2.2 µF ceramic output capacitors. |
| Quiescent Current | 21 µA - extends battery life in always-on sensor nodes or standby modes where 1 mA load is typical. |
| Efficiency @ 1 mA | 83% - maintains high light-load efficiency via HyperLight Load® PFM, avoiding efficiency collapse common in standard buck regulators. |
| Output Ripple | 14 mVPP in HyperLight Load® mode - meets low-noise analog supply requirements without additional LC filtering. |
| Shutdown Current | 0.01 µA - ensures negligible battery drain during system sleep or power-off states. |
Pinout & Package
Package: 1.6 mm × 1.6 mm, 6-lead TDFN with exposed thermal pad (ePAD), rated for –40°C to +125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Input Power Supply | Accepts 2.7–5.5 V; requires ≥2.2 µF ceramic bypass capacitor placed adjacent to PGND to suppress high-frequency switching noise. |
| 2 - SW | Power Switch Node | Drives external inductor; high dv/dt node requiring short, isolated routing away from sensitive analog traces. |
| 3 - SNS | Output Voltage Sense | Direct connection to VOUT near output capacitor; critical for accurate regulation and low-noise feedback path. |
| 4 - EN | Enable Control Input | Logic-high (>0.9 V) enables regulation; logic-low (<0.5 V) shuts down IC with 0.01 µA leakage - must not float. |
| 5 - AGND | Analog Ground Reference | Low-noise ground for internal reference and error amplifier; connects to star ground point shared with CIN/COUT. |
| 6 - PGND | Power Ground Return | High-current return path for MOSFET switching; routed separately from AGND to minimize ground bounce. |
| ePAD | Thermal & Electrical Ground | Must be soldered to PCB copper pour tied to PGND for thermal dissipation and EMI reduction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC23050-GYMT-TR | Same 1.8 V fixed output, but 600 mA rating and 3.5 MHz switching frequency; larger 2.0 mm × 2.0 mm TDFN package. | Better suited for higher-current applications like dual-core microcontrollers; less optimal for ultra-thin designs requiring sub-1 mm height. | Select when >400 mA peak load or lower EMI sensitivity justifies larger footprint and reduced switching frequency. |
| TPS62231DRYR | 1.8 V fixed output, 400 mA, 3.6 MHz switching; uses different control scheme (D-CAP2) and lacks HyperLight Load®; 1.6 mm × 1.6 mm WSON package. | Higher light-load quiescent current (25 µA vs. 21 µA); 25 mVPP ripple in PFM mode vs. 14 mVPP for MIC23030-GYMT-TR. | Choose if existing TI ecosystem integration or D-CAP2's simpler layout rules outweigh the 6% efficiency loss at 1 mA and higher ripple. |
Compared with MIC23030-GYMT-TR, MIC23050-GYMT-TR trades higher current capability and lower EMI for increased board area, while TPS62231DRYR offers TI-compatible design flow at the cost of measurable light-load efficiency and ripple performance degradation.

FAQ
What is the output voltage tolerance of the MIC23030-GYMT-TR over temperature and load?
The MIC23030-GYMT-TR provides a fixed 1.8 V output with ±2.5% accuracy over full operating conditions (–40°C to +125°C junction temperature, 20 mA to 400 mA load, 2.7 V to 5.5 V input). This specification is guaranteed across temperature and load per DS20006488A-page 4, Table 1-1, and applies directly to the MIC23030-GYMT-TR variant.
Does the MIC23030-GYMT-TR require an external feedback resistor network?
No. The MIC23030-GYMT-TR is the fixed 1.8 V output version and does not use the FB pin; it integrates the feedback divider internally. Pin 5 is AGND and Pin 6 is PGND - no external resistors are needed, simplifying layout and eliminating resistor tolerance errors that affect regulation accuracy in adjustable variants like MIC23030-AYMT-TR.
What is the recommended inductor value for optimal transient response with the MIC23030-GYMT-TR?
A 0.47 µH inductor is recommended for best transient response with the MIC23030-GYMT-TR, as confirmed in DS20006488A-page 13, Section 5.3. This value shifts the HyperLight Load® to PWM transition point to ~120 mA, enabling faster recovery from load steps while maintaining compatibility with sub-1 mm height requirements.
How does the MIC23030-GYMT-TR achieve ultra-low output ripple in HyperLight Load® mode?
The MIC23030-GYMT-TR achieves 14 mVPP ripple in HyperLight Load® mode through its proprietary minimum on/off-time control architecture, which minimizes switching artifacts and leverages the integrated low-RDS(ON) MOSFETs to reduce voltage spikes. This behavior is measured and specified in DS20006488A-page 1, Features section, and applies specifically to the MIC23030-GYMT-TR fixed-output variant.
Is the ePAD on the MIC23030-GYMT-TR electrically connected to PGND or AGND?
The ePAD on the MIC23030-GYMT-TR is electrically connected to PGND, as shown in the functional block diagram (DS20006488A-page 3) and package outline (DS20006488A-page 17). It must be soldered to a PCB thermal pad tied to the PGND net to ensure proper thermal dissipation and EMI suppression - not to AGND or floating.
