Product details
Overview
MIC33030-GYHJ-TR from Microchip Technology is a fixed 1.8 V, 400 mA synchronous buck regulator with integrated inductor, HyperLight Load® mode, 8 MHz PWM operation, ±2.5% output voltage accuracy over temperature, and 21 µA quiescent current - designed for powering processor cores in space-constrained portable electronics.
For engineers reviewing the MIC33030-GYHJ-TR datasheet, MIC33030-GYHJ-TR pinout, MIC33030-GYHJ-TR application, or MIC33030-GYHJ-TR equivalent, key selection considerations include its internal inductor architecture, ultra-low light-load efficiency (78% at 1 mA), 30 mVPP ripple in HyperLight Load® mode, 2.5 mm × 2.0 mm HJDFN package, and thermal shutdown/current-limit protection.
Technical Context
The MIC33030-GYHJ-TR implements a proprietary HyperLight Load® control scheme combining minimum on-time/off-time PFM for light loads and fixed-frequency 8 MHz PWM for higher loads, enabling seamless transition near ~150 mA. It integrates both high-side PMOS and low-side NMOS switches with 0.65 Ω / 0.8 Ω RDS(ON), eliminating external inductor and simplifying layout to two ceramic capacitors only.
Its dual-ground architecture separates analog ground (AGND) and power ground (PGND), while the SNS pin enables precise remote sensing at the output capacitor. The device operates across –40°C to +125°C junction temperature with undervoltage lockout (2.45–2.65 V) and thermal shutdown at 160°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V - eliminates external feedback resistors and ensures stable core supply for SoCs/FPGAs. |
| Max Output Current | 400 mA - supports mid-tier application processors and wireless baseband ICs without external current boosting. |
| Input Voltage Range | 2.7 V to 5.5 V - compatible with single-cell Li-ion (3.0–4.2 V), USB 5 V, and regulated 3.3 V rails. |
| Quiescent Current | 21 µA typical - extends battery life in always-on subsystems like GPS receivers or Bluetooth co-processors. |
| Switching Frequency | Up to 8 MHz - enables use of tiny 2.2 µF output capacitors and minimizes EMI filtering requirements. |
| Output Ripple | 30 mVPP in HyperLight Load® mode - maintains clean supply under dynamic sleep/active transitions in mobile devices. |
| Junction Temp Range | –40°C to +125°C - qualified for automotive infotainment and industrial handheld environments. |
Pinout & Package
Package: 10-lead 2.5 mm × 2.0 mm × 1.15 mm HJDFN with exposed thermal pad (ePAD), RoHS-compliant and Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SNS (Pin 1) | Sense input | Connects directly to VOUT near output capacitor for accurate regulation; critical for load transient stability. |
| NC (Pin 2) | No connect | Not internally bonded - must be left unconnected or tied to PGND per layout best practice. |
| EN (Pin 3) | Enable control | Logic-high active; 0.9 V threshold with 35 mV hysteresis - supports direct GPIO control without level-shifting. |
| SW (Pins 4,5) | Internal switch node | Connects to internal inductor; not routed externally - eliminates inductor placement and EMI loop concerns. |
| VOUT (Pins 6,7) | Regulated output | Delivers 1.8 V to load; requires ≥2.2 µF ceramic capacitor placed adjacent to pin for ripple suppression. |
| PGND (Pin 8) | Power ground return | Carries high-switching-current return path; must be connected to ePAD and separated from AGND loop. |
| AGND (Pin 9) | Analog reference ground | Provides low-noise bias for error amplifier and reference - must be star-connected to minimize noise coupling. |
| VIN (Pin 10) | Input supply | Accepts 2.7–5.5 V; requires ≥2.2 µF bypass capacitor between VIN and PGND to suppress high-frequency switching noise. |
| ePAD | Thermal & electrical ground | Must be soldered to PCB thermal pad connected to PGND plane - essential for thermal performance (θJA = 76°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated inductor | Eliminates external inductor, reducing solution size to < 12 mm² and removing inductor selection, saturation, and EMI tuning effort. |
| HyperLight Load® mode | Enables 78% efficiency at 1 mA load - ideal for deep-sleep states in portable navigation and media players. |
| Ultra-fast transient response | Stabilizes within < 10 µs after 0–400 mA load step - prevents brownout during CPU burst activity. |
| Low-output-voltage ripple | 7 mV ripple in full PWM mode - meets tight noise budgets for RF front-ends and high-speed ADCs. |
| Thermal & current protection | Auto-recovery thermal shutdown at 160°C and cycle-by-cycle current limit - ensures robustness under overload or poor heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC33030-JYHJ-TR | Fixed 2.5 V output; identical package, pinout, and specs except VOUT. | Used where higher core voltage required (e.g., legacy DSPs); not drop-in for 1.8 V systems. | Select only if target load requires 2.5 V - no circuit modification needed beyond output capacitor recheck. |
| MIC33030-4YHJ-TR | Fixed 1.2 V output; same thermal and electrical characteristics, differing only in feedback network calibration. | Targets ultra-low-power microcontrollers and memory interfaces requiring 1.2 V logic rails. | Valid alternative only when system-level VOUT tolerance allows 1.2 V - verify load compatibility before substitution. |

FAQ
What is the output voltage of the MIC33030-GYHJ-TR?
The MIC33030-GYHJ-TR delivers a fixed 1.8 V output voltage, factory-trimmed to ±2.5% accuracy over temperature and line/load conditions. This value is encoded in the part number suffix 'G' per Microchip's identification system and does not require external feedback components - the MIC33030-GYHJ-TR is configured as a fixed-output regulator at 1.8 V.
Does the MIC33030-GYHJ-TR require an external inductor?
No, the MIC33030-GYHJ-TR integrates the power inductor internally, eliminating the need for any external magnetic component. This architecture reduces solution size to just two external ceramic capacitors (input and output), simplifies layout, and removes inductor-related design variables such as DCR, saturation current, and EMI shielding - a defining feature of the MIC33030-GYHJ-TR.
What is the maximum operating junction temperature for the MIC33030-GYHJ-TR?
The MIC33030-GYHJ-TR is rated for a junction temperature range of –40°C to +125°C. Thermal shutdown activates at +160°C with 20°C hysteresis, and the package thermal resistance is θJA = 76°C/W (measured on standard JEDEC 2S2P test board). Proper PCB thermal pad connection to PGND is required to maintain safe operation at full 400 mA load in ambient temperatures up to +85°C.
How does HyperLight Load® mode improve efficiency in the MIC33030-GYHJ-TR?
HyperLight Load® mode in the MIC33030-GYHJ-TR uses pulse-frequency modulation (PFM) with minimum on/off time control to deliver energy only when needed, achieving 78% efficiency at 1 mA load and 21 µA quiescent current. This contrasts with conventional PWM, which would waste power cycling at full frequency - making the MIC33030-GYHJ-TR especially effective in battery-powered devices with intermittent high-current demand.
What are the recommended input and output capacitors for the MIC33030-GYHJ-TR?
Microchip specifies a minimum 2.2 µF X5R/X7R ceramic capacitor for both input (between VIN and PGND) and output (between VOUT and PGND). A 4.7 µF 0603 TDK C1608X5R0J475K is recommended for optimal performance. Y5V/Z5U types are discouraged due to capacitance drift and high-frequency resistance - these values apply specifically to the MIC33030-GYHJ-TR and are validated in its datasheet Figures 5-1 and 5-2.
