Product details
Overview
MIC23030-AYMT-TR from Microchip Technology is an adjustable-output, 8 MHz synchronous buck regulator delivering up to 400 mA output current with HyperLight Load® mode for ultra-fast transient response and high light-load efficiency. It operates from 2.7V to 5.5V input, achieves 91% peak efficiency at full load and 83% at 1 mA, and targets processor core voltage regulation in space-constrained portable electronics.
For engineers reviewing the MIC23030-AYMT-TR datasheet, MIC23030-AYMT-TR pinout, MIC23030-AYMT-TR application, or MIC23030-AYMT-TR equivalent, this page delivers verified technical context, validated pin functions, real-world application mapping, and confirmed alternative options for low-voltage, high-efficiency DC/DC conversion in battery-powered embedded systems.
Technical Context
The MIC23030-AYMT-TR implements a proprietary HyperLight Load® control architecture combining minimum on-time/off-time pulse frequency modulation (PFM) at light loads and fixed-frequency 8 MHz PWM in continuous conduction mode. Its integrated PMOS/NMOS synchronous switches enable zero-voltage switching transitions and eliminate external diode losses.
This dual-mode operation ensures stable regulation across 1 mA to 400 mA load range while maintaining ≤14 mVPP output ripple in HyperLight Load® mode and ≤5 mVPP in full PWM mode - enabled by precise 0.62 V feedback reference and internal current-sense amplifier with 0.41 A–1 A current-limit threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion, USB 3.0, and regulated 3.3 V/5 V rails without external LDO pre-regulation. |
| Output Current | 400 mA maximum - sufficient for ARM Cortex-M cores, low-power FPGAs, and RF transceivers in portable devices. |
| Switching Frequency | 8 MHz nominal in PWM mode - enables use of sub-1 mm height 0.47 µH inductors and compact 2.2 µF ceramic output capacitors. |
| Quiescent Current | 21 µA typical - extends battery life in always-on sensor nodes and standby modes without sacrificing startup speed. |
| Feedback Reference | 0.62 V ±1.5% - sets adjustable output voltage via external resistor divider; enables 0.7 V to 3.6 V output range with <±2.5% accuracy. |
| Thermal Range | –40°C to +125°C junction - qualified for automotive infotainment modules, industrial handhelds, and GPS receivers. |
| Shutdown Current | 0.01 µA - reduces system leakage during deep sleep, critical for multi-year battery operation in IoT edge sensors. |
Pinout & Package
Package: 6-lead 1.6 mm × 1.6 mm TDFN with exposed thermal pad (ePAD), rated θJA = 92.4°C/W. Designed for minimal PCB footprint and efficient heat dissipation in thin-profile portable assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | 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. |
| SW (Pin 2) | Power Switch Node | Drives external inductor; carries high di/dt current; must be routed short and away from analog traces to avoid EMI coupling. |
| SNS (Pin 3) | Output Voltage Sense | Direct connection to VOUT near output capacitor; provides precision feedback path for regulation and load-transient compensation. |
| EN (Pin 4) | Enable Control Input | Logic-high (>0.9 V) enables regulation; logic-low (<0.5 V) shuts down device to 0.01 µA; must not float - tie to GND or microcontroller GPIO. |
| AGND (Pin 5) | Analog Ground Reference | Low-noise ground return for internal error amplifier and reference; separate from PGND to prevent switching noise injection into feedback loop. |
| PGND (Pin 6) | Power Ground Return | High-current return path for VIN and SW; connects to ePAD and input/output capacitor grounds; forms tight loop with VIN and SW traces. |
Key Features
| Feature | Design Value |
|---|---|
| HyperLight Load® Mode | Enables PFM operation below ~30–120 mA (inductor-dependent), sustaining >83% efficiency at 1 mA while delivering ultra-fast load transient recovery (<10 µs). |
| Integrated Synchronous MOSFETs | Eliminates external Schottky diode; reduces conduction loss with 0.65 Ω (PMOS) and 0.8 Ω (NMOS) RDS(ON), improving full-load efficiency to 91%. |
| Ultra-Low Output Ripple | 14 mVPP in HyperLight Load® mode and 5 mVPP in PWM mode - allows use of small 2.2 µF X5R/X7R ceramic capacitors without LC filtering stages. |
| Thermal & Current Protection | Includes 160°C overtemperature shutdown with 20°C hysteresis and cycle-by-cycle current limiting (0.41–1.0 A threshold) to prevent damage under overload or short-circuit. |
| Soft-Start Function | 100 µs internal soft-start prevents inrush current and output overshoot during power-up - eliminates need for external timing components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable-output buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62840DLCR | 2.7–6.5 V input, 1.8 A output, 1.8 MHz switching, 150 nA IQ - higher current but lower frequency and larger solution size. | Better suited for higher-power MCU applications; less optimal for ultra-thin designs requiring 8 MHz and 1.6 mm × 1.6 mm footprint. | Select when >400 mA output or extended input range beyond 5.5 V is required; verify layout compatibility with larger TQFN package. |
| MAX77324EWA+T | 2.5–5.5 V input, 600 mA output, 2.5 MHz switching, 2.5 µA IQ - higher IQ, lower frequency, different pinout (no AGND/PGND separation). | Lacks dedicated analog/power ground separation and HyperLight Load® architecture - exhibits slower transient response and higher light-load ripple. | Choose for cost-sensitive designs where 8 MHz operation and sub-15 mVPP ripple are not mandatory; confirm thermal derating at 400 mA in 1.6 mm × 1.6 mm footprint. |
Compared with TPS62840DLCR and MAX77324EWA+T, the MIC23030-AYMT-TR uniquely balances ultra-small 1.6 mm × 1.6 mm TDFN packaging, 8 MHz operation enabling sub-millimeter height, and HyperLight Load® mode delivering both 83% efficiency at 1 mA and <10 µs transient recovery - making it optimal for next-generation wearable and hearable devices.

FAQ
What output voltage range does the MIC23030-AYMT-TR support?
The MIC23030-AYMT-TR is an adjustable-output buck regulator with a feedback reference voltage of 0.62 V. Using an external resistor divider, it supports output voltages from 0.7 V to 3.6 V. This range covers common processor core voltages (e.g., 0.8 V, 1.0 V, 1.2 V) and I/O rails (1.8 V, 2.5 V, 3.3 V), all while maintaining ±2.5% output accuracy across temperature and load conditions.
How does HyperLight Load® mode improve efficiency in the MIC23030-AYMT-TR?
HyperLight Load® mode enables pulse frequency modulation (PFM) operation at light loads (typically <30–120 mA, depending on inductor value), reducing switching activity only when needed. This cuts gate-drive and transition losses, allowing the MIC23030-AYMT-TR to achieve 83% efficiency at 1 mA - significantly higher than conventional PWM-only regulators - while maintaining ultra-fast transient response and low output ripple.
What is the recommended inductor value for the MIC23030-AYMT-TR?
Microchip specifies a supported inductor range of 0.47 µH to 2.2 µH for the MIC23030-AYMT-TR. A 0.47 µH inductor optimizes transient response and minimizes solution height, while a 2.2 µH inductor reduces output ripple and improves efficiency above 100 mA. The choice directly affects the load threshold at which the device transitions from HyperLight Load® (PFM) to fixed-frequency PWM mode.
Does the MIC23030-AYMT-TR require external compensation components?
No, the MIC23030-AYMT-TR is internally compensated and designed to be stable with standard ceramic output capacitors (≥2.2 µF, X5R/X7R) and inductors from 0.47 µH to 2.2 µH. No external compensation network is needed - simplifying design, reducing BOM count, and eliminating tuning effort typically required in voltage-mode or current-mode controllers.
What protection features are built into the MIC23030-AYMT-TR?
The MIC23030-AYMT-TR integrates thermal shutdown (160°C with 20°C hysteresis), cycle-by-cycle current limiting (0.41–1.0 A threshold), undervoltage lockout (2.45–2.65 V turn-on), and soft-start (100 µs). These features protect the IC and downstream circuitry during fault conditions such as output short, excessive ambient temperature, or input brownout - without requiring external supervision circuits.
