Product details
Overview
MIC23030-CYMT-TR from Microchip Technology is a 1.0 V fixed-output, 400 mA synchronous buck regulator with HyperLight Load® mode, operating from 2.7 V to 5.5 V input and delivering up to 91% efficiency at full load. It features 8 MHz PWM switching, 21 µA quiescent current, and ultra-fast transient response-designed for powering processor cores in space-constrained portable electronics.
For engineers reviewing the MIC23030-CYMT-TR datasheet, MIC23030-CYMT-TR pinout, MIC23030-CYMT-TR application, or MIC23030-CYMT-TR equivalent, this page delivers verified specifications, validated package mapping, confirmed pin functions, and real-world application context for low-voltage core rail design in battery-powered embedded systems.
Technical Context
The MIC23030-CYMT-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 (CCM). Its integrated PMOS/NMOS synchronous switches enable high efficiency across 1 mA–400 mA load range without external diodes.
It uses a dedicated SNS pin for output voltage sensing near the capacitor, separate AGND and PGND paths for noise isolation, and built-in thermal shutdown (160°C) and current-limit protection (0.41–1 A). The device transitions into CCM at ~120 mA when using a 0.47 µH inductor and maintains ±2.5% output voltage accuracy over line, load, and 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 pre-regulation. |
| Output Voltage | Fixed 1.0 V - factory-trimmed for processor core supply; eliminates external feedback resistors and layout sensitivity. |
| Max Output Current | 400 mA - sufficient for ARM Cortex-M4/M7 cores, DSPs, and FPGA I/O banks in portable designs. |
| Switching Frequency | 8 MHz (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 - ensures >83% efficiency at 1 mA, critical for standby power in always-on sensor nodes. |
| Output Ripple | 14 mVPP (HyperLight Load®), 5 mV (PWM mode) - meets tight analog/RF supply noise requirements without additional LDO post-regulation. |
| Junction Temp Range | –40°C to +125°C - qualified for automotive infotainment modules and industrial handhelds. |
| Package | 1.6 mm × 1.6 mm, 6-pin TDFN - footprint compatible with 0201 passives; ePAD enhances thermal dissipation. |
Pinout & Package
Package: 1.6 mm × 1.6 mm, 6-lead TDFN with exposed thermal pad (ePAD), RoHS-compliant matte tin finish. Pin 1 identified by dot; ePAD must be connected to PGND for optimal thermal performance and EMI suppression.
| 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; high dv/dt node requiring short, isolated routing away from analog/sensitive traces. |
| SNS (Pin 3) | Output Voltage Sense | Direct connection to VOUT near output capacitor; enables accurate regulation independent of PCB trace resistance. |
| EN (Pin 4) | Enable Control Input | Logic-high (>0.9 V) enables regulation; logic-low (<0.5 V) reduces supply current to 0.01 µA; must not float. |
| AGND (Pin 5) | Analog Ground Reference | Low-noise ground return for internal error amplifier and reference; routed separately from PGND to avoid coupling switching transients. |
| PGND (Pin 6) | Power Ground Return | High-current return path for VIN and SW; connects to ePAD and input/output capacitor grounds to minimize loop area and EMI. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC23050-CYMT-TR | Same 1.0 V fixed output, but rated for 600 mA; higher RDS(ON) (0.75 Ω vs. 0.65 Ω) and 25 µA IQ. | Better suited for higher-current SoCs; less optimal for ultra-low-power sleep modes due to higher quiescent draw. | Select MIC23050-CYMT-TR only if peak load exceeds 400 mA; otherwise MIC23030-CYMT-TR offers superior light-load efficiency. |
| TPS62231CDBVR | 1.0 V fixed, 400 mA, 3.6 MHz switching; 22 µA IQ; no HyperLight Load®; uses conventional PFM/PWM hybrid control. | Larger inductor required (≥1.0 µH); higher light-load ripple (~25 mVPP); lacks dedicated SNS pin for remote sensing. | Choose TPS62231CDBVR only if lower EMI priority outweighs size/efficiency trade-offs; MIC23030-CYMT-TR provides superior transient response and smaller solution size. |
Compared with MIC23050-CYMT-TR and TPS62231CDBVR, the MIC23030-CYMT-TR delivers the lowest solution footprint and best light-load efficiency for 1.0 V core rails, thanks to its 8 MHz switching, HyperLight Load® architecture, and 1.6 mm × 1.6 mm TDFN package-making it optimal for space- and battery-life-constrained portable designs.

FAQ
What is the output voltage tolerance of the MIC23030-CYMT-TR over temperature and load?
The MIC23030-CYMT-TR maintains ±2.5% output voltage accuracy across –40°C to +125°C junction temperature, 2.7 V to 5.5 V input, and 20 mA to 400 mA load conditions. This specification is guaranteed in production testing and applies to the fixed 1.0 V output version; no external resistor network is required or supported for MIC23030-CYMT-TR.
Does the MIC23030-CYMT-TR require an external feedback resistor divider?
No, the MIC23030-CYMT-TR is a fixed 1.0 V output variant and does not use the FB pin. It employs internal trimming and the SNS pin for direct output sensing-eliminating external resistors, reducing layout sensitivity, and improving regulation accuracy compared to adjustable versions like MIC23030-AYMT-TR.
What is the recommended inductor value for optimal efficiency in the MIC23030-CYMT-TR?
For balanced efficiency, size, and transient response, Microchip recommends a 0.47 µH inductor with 400 mA saturation current and low DCR (e.g., Coilcraft XAL5030-471MEB). This value enables the MIC23030-CYMT-TR to transition into PWM mode at ~120 mA, maximizing 8 MHz efficiency while retaining HyperLight Load® benefits below that threshold.
How does the MIC23030-CYMT-TR achieve ultra-low output ripple?
The MIC23030-CYMT-TR achieves 5 mV output ripple in PWM mode and 14 mVPP in HyperLight Load® mode through its proprietary control architecture, integrated low-RDS(ON) MOSFETs (0.65 Ω PMOS / 0.8 Ω NMOS), and dedicated SNS pin for precise remote sensing-allowing effective regulation with only a 2.2 µF ceramic output capacitor.
Can the MIC23030-CYMT-TR operate with a 2.5 V input supply?
Yes, the MIC23030-CYMT-TR operates down to 2.7 V input per its absolute minimum rating; 2.5 V is below specification and may cause undervoltage lockout (VUVLO = 2.45–2.65 V) or unstable regulation. For 2.5 V input systems, consider using a higher-VIN-rated buck or adding a pre-bias start-up circuit-MIC23030-CYMT-TR must see ≥2.7 V at VIN to function reliably.
