Product details
Overview
MIC33030-AYHJ-TR from Microchip Technology is an adjustable-output, 400 mA synchronous buck regulator with integrated inductor, operating from 2.7V to 5.5V input and delivering ±2.5% output voltage accuracy over temperature. It features HyperLight Load® mode for 78% efficiency at 1 mA, 21 µA quiescent current, and ultra-fast transient response-designed for powering processor cores in space-constrained portable electronics.
For engineers reviewing the MIC33030-AYHJ-TR datasheet, MIC33030-AYHJ-TR pinout, MIC33030-AYHJ-TR application, or MIC33030-AYHJ-TR equivalent, key selection criteria include internal inductor integration, 10-lead HJDFN package footprint, adjustable feedback (0.62 V reference), thermal shutdown, and compatibility with 2.2 µF output capacitors in battery-powered systems requiring low-noise, high-efficiency DC/DC conversion.
Technical Context
The MIC33030-AYHJ-TR implements a proprietary HyperLight Load® control architecture combining minimum on-time/off-time PFM operation at light loads and fixed-frequency 8 MHz PWM in continuous conduction mode above ~150 mA. Its internal 0.36 µH inductor eliminates external magnetics while enabling stable regulation with only two ceramic capacitors.
It integrates fully synchronous PMOS/NMOS power switches with 0.65 Ω high-side and 0.8 Ω low-side RDS(ON), supports adjustable output via FB pin with 0.62 V internal reference, and includes undervoltage lockout (2.45–2.65 V), soft-start (100 µs), and thermal shutdown (160 °C) with 20 °C hysteresis.
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 Current | 400 mA - Sustained load capability sufficient for ARM Cortex-M core supplies and FPGA I/O banks. |
| Output Voltage Accuracy | ±2.5% - Tight tolerance ensures reliable operation of sensitive digital logic across –40°C to +125°C junction range. |
| Quiescent Current | 21 µA - Enables >1-year battery life in always-on sensor nodes powered by coin cells or small Li-ion packs. |
| Switching Frequency | Up to 8 MHz - Allows use of tiny 2.2 µF output capacitors and minimizes EMI filter size in RF-sensitive layouts. |
| Feedback Reference | 0.62 V - Enables precise adjustable outputs from 0.7 V to 3.6 V using standard resistor dividers; simplifies multi-rail sequencing. |
| Thermal Shutdown | 160 °C with 20 °C hysteresis - Protects against sustained overload or poor PCB thermal design without latch-up. |
Pinout & Package
Package: 10-lead 2.5 mm × 2.0 mm × 0.8 mm HJDFN with exposed thermal pad (ePAD), rated for –40°C to +125°C junction temperature and 76 °C/W θJA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SNS | Sense Input | Direct connection to VOUT near output capacitor; enables accurate remote sensing and load regulation independent of PCB trace IR drop. |
| NC | No Connect | Pin 2 is unconnected internally; must be left floating or tied to AGND per layout best practice-no routing required. |
| EN | Enable Control | Logic-compatible input (0.5–1.2 V threshold); asserts shutdown state drawing only 0.01 µA, enabling system-level power gating. |
| SW | Internal Switch Node | Connects to internal inductor; not routed externally-eliminates loop area and EMI concerns associated with discrete inductor switching nodes. |
| VOUT | Regulated Output | Main power delivery node; requires ≥2.2 µF X5R/X7R ceramic capacitor placed adjacent to pin for stability and ripple suppression. |
| PGND | Power Ground Return | High-current return path for MOSFET switching; must be separated from AGND and connected directly to ePAD for thermal performance. |
| AGND | Analog Ground Reference | Low-noise reference for error amplifier and feedback circuitry; requires dedicated ground plane region isolated from PGND. |
| VIN | Input Supply | Accepts 2.7–5.5 V; requires ≥2.2 µF bypass capacitor placed between VIN and PGND within 2 mm of the pin. |
| FB | Feedback Input | Adjustable output configuration only; accepts resistor divider to set VOUT = 0.62 V × (1 + R1/R2); enables flexible rail generation. |
| ePAD | Thermal & Electrical Ground | Exposed pad under package body; must be soldered to large PGND copper area for thermal dissipation and EMI reduction. |

FAQ
What is the output voltage range supported by the MIC33030-AYHJ-TR?
The MIC33030-AYHJ-TR supports an adjustable output voltage range from 0.7 V to 3.6 V, set via an external resistor divider connected to the FB pin. Its internal 0.62 V feedback reference enables precise regulation across this range, with ±2.5% accuracy over temperature and load-making MIC33030-AYHJ-TR suitable for powering modern low-voltage logic cores and I/O interfaces.
Does the MIC33030-AYHJ-TR require an external inductor?
No, the MIC33030-AYHJ-TR integrates a 0.36 µH inductor internally, eliminating the need for any external magnetic component. This reduces total solution size to under 12 mm² and simplifies layout by removing high-current switch-node routing-key advantages of MIC33030-AYHJ-TR over conventional buck controllers requiring discrete inductors.
What is the maximum allowable input voltage for the MIC33030-AYHJ-TR?
The absolute maximum input voltage for the MIC33030-AYHJ-TR is +6 V, but its recommended operating range is +2.7 V to +5.5 V. Exceeding 5.5 V may trigger undervoltage lockout hysteresis or cause reliability issues; operation within the specified range ensures full performance compliance-including 400 mA output, ±2.5% accuracy, and HyperLight Load® functionality-as documented for MIC33030-AYHJ-TR.
How does the MIC33030-AYHJ-TR achieve ultra-low quiescent current?
The MIC33030-AYHJ-TR achieves 21 µA typical quiescent current through optimized bias circuitry and adaptive gate drive in HyperLight Load® mode, where switching occurs only as needed to maintain regulation. In shutdown, it draws just 0.01 µA. This behavior is intrinsic to MIC33030-AYHJ-TR's architecture-not dependent on external components-and enables multi-year battery life in always-on applications.
Can the MIC33030-AYHJ-TR be used with ceramic output capacitors smaller than 4.7 µF?
Yes, the MIC33030-AYHJ-TR is designed to be stable with a minimum 2.2 µF X5R or X7R ceramic output capacitor. While 4.7 µF improves transient response and reduces ripple, using 2.2 µF is fully supported per datasheet specifications and maintains stability across –40°C to +125°C-confirming MIC33030-AYHJ-TR's suitability for ultra-compact designs where every millimeter counts.
