Product details
Overview
MIC23030-4YMT-TR from Microchip Technology is a 1.2 V fixed-output, 400 mA synchronous buck regulator operating from 2.7 V to 5.5 V input, featuring HyperLight Load® mode for ultra-fast transient response and up to 91% peak efficiency at 8 MHz PWM switching. It delivers low-noise core power to processor subsystems in space-constrained portable electronics.
For engineers reviewing the MIC23030-4YMT-TR datasheet, MIC23030-4YMT-TR pinout, MIC23030-4YMT-TR application, or MIC23030-4YMT-TR equivalent, key selection criteria include its 1.2 V fixed output, 1.6 mm × 1.6 mm TDFN-6 package, 21 µA quiescent current, 14 mVPP ripple in HyperLight Load® mode, and thermal shutdown protection across –40°C to +125°C junction temperature.
Technical Context
The MIC23030-4YMT-TR implements a proprietary HyperLight Load® control architecture combining minimum on/off-time PFM at light loads and constant-frequency 8 MHz PWM in continuous conduction mode above ~120 mA (with 0.47 µH inductor). Its integrated PMOS/NMOS synchronous switches eliminate external diode requirements and enable high efficiency down to 1 mA load.
This regulator uses voltage-mode control with internal 0.62 V reference and fixed 1.2 V output set by factory-trimmed feedback network. It features soft-start (100 µs), undervoltage lockout (2.55 V typical), and overtemperature shutdown (160°C) with 20°C hysteresis - all optimized for battery-powered applications requiring stable core rail generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2.5% - eliminates external resistor divider and ensures precise core supply for low-voltage processors. |
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion (3.0–4.2 V), USB 5 V, and regulated 3.3 V rails without external LDO pre-regulation. |
| Max Output Current | 400 mA - sufficient for ARM Cortex-M cores, DSPs, and RF SoCs in portable devices. |
| Switching Frequency | 8 MHz nominal in 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 typical - extends battery life in standby modes while maintaining fast wake-up capability. |
| Shutdown Current | 0.01 µA - reduces system leakage during deep sleep or power-off states. |
| Output Ripple | 14 mVPP in HyperLight Load® mode - meets tight noise budgets for analog/RF sections without additional filtering. |
Pinout & Package
Package: 6-lead 1.6 mm × 1.6 mm TDFN with exposed thermal pad (ePAD), rated for –40°C to +125°C junction temperature. Pin 1 identified by dot marking; ePAD must be soldered to PGND for thermal and electrical performance.
| 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 inductor; carries high di/dt current; must be routed short and away from sensitive analog traces to minimize EMI coupling. |
| SNS (Pin 3) | Output voltage sense | Direct connection to VOUT near output capacitor ensures accurate regulation under load transients; critical for stability with small ceramics. |
| 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 controller GPIO. |
| AGND (Pin 5) | Analog ground reference | Separate low-noise return path for internal error amplifier and reference; connects to central star ground point shared with CIN/COUT. |
| PGND (Pin 6) | Power ground return | High-current return for MOSFET switching; requires low-inductance PCB copper pour connected directly to ePAD and input/output capacitors. |
Key Features
| Feature | Design Value |
|---|---|
| HyperLight Load® mode | Enables >83% efficiency at 1 mA while delivering ultra-fast load transient response - essential for burst-mode processor operation. |
| Fully integrated MOSFETs | Eliminates external high-side PMOS and low-side NMOS, reducing BOM count and layout complexity in 1.6 mm × 1.6 mm footprint. |
| Low output voltage ripple | 14 mVPP (HL mode) and 5 mV (PWM mode) - allows use of compact 2.2 µF X5R/X7R output capacitors without compromising noise-sensitive circuits. |
| Thermal & current protection | Includes foldback current limit (0.41–1 A) and thermal shutdown (160°C) with 20°C hysteresis - prevents damage during overload or poor heatsinking. |
| Soft-start timing | 100 µs controlled ramp - prevents inrush current and output overshoot during power-up, protecting downstream logic and memory. |

|---|---|---|---|
| TPS62231DRYT | 1.2 V fixed, 400 mA, 3–6 V input, 2.25 MHz switching, 22 µA IQ, 10-pin WSON | Lower switching frequency requires larger inductor; lacks HyperLight Load® architecture for ultra-light-load efficiency | Select when board space permits larger magnetics and 2.25 MHz operation aligns with system EMI requirements. |

FAQ
What is the output voltage tolerance of the MIC23030-4YMT-TR?
The MIC23030-4YMT-TR provides a fixed 1.2 V output with ±2.5% accuracy over temperature, line, and load conditions (VIN = 3.6 V, ILOAD = 20 mA). This tolerance is guaranteed across the full –40°C to +125°C junction temperature range and ensures reliable core voltage delivery to modern low-voltage processors without external trimming.
Does the MIC23030-4YMT-TR require an external feedback resistor network?
No, the MIC23030-4YMT-TR does not require external feedback resistors. As a fixed 1.2 V output variant, it integrates the feedback divider internally. Only the adjustable versions (e.g., MIC23030-AYMT) use the FB pin and external resistors; the MIC23030-4YMT-TR uses SNS directly connected to VOUT for sensing.
What is the recommended inductor value for the MIC23030-4YMT-TR?
Microchip recommends a 0.47 µH to 2.2 µH shielded ceramic inductor for the MIC23030-4YMT-TR. A 0.47 µH inductor optimizes transient response and enables the smallest solution height, while a 2.2 µH inductor reduces output ripple and improves light-load efficiency - both are fully supported without compensation changes.
How does HyperLight Load® mode improve efficiency at light loads?
HyperLight Load® mode enables the MIC23030-4YMT-TR to operate in pulse-frequency modulation (PFM) at light loads, reducing switching losses by only activating the power stage when needed. This achieves 83% efficiency at 1 mA - significantly higher than conventional PWM-only regulators - while maintaining ultra-fast transient recovery.
Is thermal pad (ePAD) connection required for MIC23030-4YMT-TR operation?
Yes, the exposed thermal pad (ePAD) on the MIC23030-4YMT-TR must be soldered to a PGND copper pour. It serves as the primary thermal and electrical return path for power ground. Omitting ePAD connection degrades thermal performance, increases junction temperature, and risks premature thermal shutdown under sustained 400 mA load.
