Product details
Overview
MIC23030-FYMT-TR from Microchip Technology is a 1.5 V fixed-output, 400 mA synchronous buck regulator operating from 2.7 V to 5.5 V input, featuring 8 MHz PWM switching, HyperLight Load® mode for ultra-fast transient response, and 21 µA quiescent current - designed for core voltage regulation in portable processors and low-power embedded systems.
For engineers reviewing the MIC23030-FYMT-TR datasheet, MIC23030-FYMT-TR pinout, MIC23030-FYMT-TR application, or MIC23030-FYMT-TR equivalent, this page delivers verified electrical parameters, validated TDFN-6 package mapping, confirmed thermal and efficiency behavior across load range, and real-world design constraints for sub-1 mm height power solutions.
Technical Context
The MIC23030-FYMT-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 seamless transition between high-efficiency light-load operation (83% at 1 mA) and high-performance full-load regulation (91% peak). Its integrated PMOS/NMOS synchronous switches eliminate external diode losses.
It uses a dedicated SNS pin for output voltage sensing with Kelvin connection capability, separate AGND and PGND pins for noise isolation, and features built-in soft-start (100 µs), thermal shutdown (160°C), and current-limit protection (0.41–1 A). The fixed 1.5 V output eliminates external feedback resistors while retaining full compatibility with adjustable variants' PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion, USB 3.3 V/5 V, and regulated 3.3 V rails without external LDO pre-regulation. |
| Output Voltage | Fixed 1.5 V ±2.5% - eliminates external resistor divider, reduces BOM count, and ensures stable core supply for low-voltage logic and memory interfaces. |
| Max Output Current | 400 mA continuous - sufficient for ARM Cortex-M cores, FPGA I/O banks, and Wi-Fi SoCs in portable form factors. |
| Switching Frequency | 8 MHz nominal in PWM mode - enables use of ultra-small 0.47 µH inductors and 2.2 µF ceramic capacitors for <1 mm solution height. |
| Quiescent Current | 21 µA typical - extends battery life in always-on sensor nodes and standby modes without sacrificing startup speed. |
| Efficiency @ 1 mA | 83% - achieved via HyperLight Load® PFM mode, critical for maintaining runtime in intermittent wake-up applications like BLE beacons. |
| Thermal Shutdown | 160°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design while allowing safe recovery after cooling. |
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 and θJA = 92.4°C/W.
| 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; carries high di/dt current - must be routed short and away from sensitive analog traces to avoid EMI coupling. |
| 3 - SNS | Output Voltage Sense | Kelvin-sense connection to VOUT near output capacitor; enables accurate regulation independent of PCB trace resistance or load current. |
| 4 - EN | Enable Control Input | Logic-compatible (0.5–1.2 V threshold); pulls device into 0.01 µA shutdown state when low - must not float to prevent erratic operation. |
| 5 - AGND | Analog Ground Reference | Low-noise return path for internal error amplifier and reference; should connect to star ground point separate from high-current PGND loop. |
| 6 - PGND | Power Ground Return | High-current return for MOSFET switching path; requires low-inductance connection to input/output capacitors to minimize voltage spikes. |
Key Features
| Feature | Design Value |
|---|---|
| HyperLight Load® Mode | Enables pulse-frequency modulation below ~120 mA, delivering 83% efficiency at 1 mA and ultra-fast load transient response (<20 µs settling). |
| Integrated Synchronous Switches | Eliminates external Schottky diode; PMOS high-side + NMOS low-side reduce conduction loss and improve efficiency over asynchronous designs. |
| Ultra-Low Output Ripple | 14 mVPP in HyperLight Load® mode and 5 mV in full PWM - allows use of small 2.2 µF X5R/X7R output capacitors without compromising stability. |
| Sub-1 mm Solution Height | Validated with 0.47 µH inductor and 2.2 µF output capacitor - meets mechanical constraints of ultra-thin wearables and compact IoT modules. |

FAQ
What is the output voltage tolerance of the MIC23030-FYMT-TR?
The MIC23030-FYMT-TR has a fixed 1.5 V output with ±2.5% accuracy over temperature and line/load conditions, as specified in the Electrical Characteristics table (VOUT = –2.5% to +2.5% at VIN = 3.6 V, ILOAD = 20 mA). This tolerance ensures reliable operation for 1.5 V logic families without requiring external trimming.
Does the MIC23030-FYMT-TR require external feedback resistors?
No, the MIC23030-FYMT-TR is a fixed-output variant and does not require external feedback resistors. Its 1.5 V regulation is implemented internally, simplifying layout and reducing BOM count. The FB pin is absent; instead, the device uses the SNS pin for output sensing and AGND/PGND separation for precision.
What inductor value is recommended for optimal efficiency with the MIC23030-FYMT-TR?
A 0.47 µH inductor is recommended for best transient response and minimal solution height, while a 2.2 µH inductor yields lower output ripple. The MIC23030-FYMT-TR is validated for stable operation with inductors from 0.47 µH to 2.2 µH, and peak efficiency (91%) is achieved with 0.47 µH at 300–400 mA loads.
How does the MIC23030-FYMT-TR achieve ultra-low quiescent current?
The MIC23030-FYMT-TR achieves 21 µA typical quiescent current through its HyperLight Load® architecture, which disables unnecessary circuitry during light-load PFM operation and employs optimized bias networks. In shutdown (EN = low), it draws only 0.01 µA - critical for battery longevity in always-on edge devices.
Is the MIC23030-FYMT-TR pin-compatible with other MIC23030 variants?
Yes, the MIC23030-FYMT-TR shares identical 6-lead TDFN package dimensions, pinout (VIN, SW, SNS, EN, AGND, PGND), and thermal pad layout with all MIC23030 variants including MIC23030-GYMT-TR and MIC23030-4YMT-TR - enabling drop-in replacement across 1.0 V, 1.2 V, 1.5 V, and 1.8 V fixed-output versions.
