Product details

Overview

MIC33030-GYHJ-T5 from Microchip Technology is a 400 mA, 8 MHz synchronous buck regulator with integrated inductor and HyperLight Load® mode, delivering fixed 1.8 V output at ±2.5% accuracy over –40°C to +125°C junction temperature, supporting ultra-low quiescent current (21 µA) and 30 mV_PP ripple in light-load mode for portable processor core supply.

For engineers reviewing the MIC33030-GYHJ-T5 datasheet, MIC33030-GYHJ-T5 pinout, MIC33030-GYHJ-T5 application, or MIC33030-GYHJ-T5 equivalent, key selection considerations include internal inductor integration, 2.5 mm × 2.0 mm HJDFN package constraints, HyperLight Load® transient response performance, and fixed 1.8 V output compatibility with mobile SoC core rails.

Technical Context

The MIC33030-GYHJ-T5 implements a proprietary asynchronous PFM/PWM hybrid control architecture: HyperLight Load® mode enables pulse-frequency modulation below ~150 mA load, while continuous conduction mode engages above that threshold with fixed 8 MHz switching frequency. It uses internal PMOS/NMOS switches with typical R_DS(ON) of 0.65 Ω (PMOS) and 0.8 Ω (NMOS), and integrates a 0.36 µH inductor.

Feedback is internally trimmed for 1.8 V fixed output-no external resistors required-while SNS pin placement mandates direct connection to the output capacitor for accurate voltage sensing. Thermal shutdown activates at 160°C with 20°C hysteresis, and undervoltage lockout triggers at 2.55 V (typ) with 100 mV hysteresis.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.8 V ±2.5% over –40°C to +125°C; eliminates need for external feedback resistors.
Max Output Current	400 mA continuous; supports single-core or dual-core mobile processors in compact form factors.
Switching Frequency	Up to 8 MHz in PWM mode; enables use of tiny 2.2 µF ceramic output capacitors and reduces EMI filtering burden.
Quiescent Current	21 µA typical; extends battery life in always-on subsystems like GPS or Bluetooth co-processors.
Output Ripple	30 mV_PP in HyperLight Load® mode; ensures stable core voltage during low-power sleep states.
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 supplies.
Package	2.5 mm × 2.0 mm × 1.15 mm 10-lead HJDFN; requires minimal PCB area and supports high-density layout.

Pinout & Package

Package: 10-lead, 2.5 mm × 2.0 mm × 1.15 mm HJDFN with exposed thermal pad (ePAD). Pin 1 marked by dot/delta; pins numbered counterclockwise from top-left corner in top view.

Pin/Terminal	Circuit Role	Design Meaning
SNS (Pin 1)	Voltage sense input	Direct connection to VOUT near output capacitor ensures accurate regulation under dynamic load; critical for low-ripple performance.
NC (Pin 2)	No-connect terminal	Internally unconnected; must remain floating-no PCB trace or solder mask opening required.
EN (Pin 3)	Enable logic input	Active-high control (0.9 V threshold typ); enables soft-start and reduces inrush; 0.01 µA shutdown current minimizes battery drain.
SW (Pins 4,5)	Internal switch node	Connects to one end of integrated inductor; not routed externally-no external inductor or SW trace needed.
VOUT (Pins 6,7)	Regulated output	Delivers 1.8 V to load; connects to SNS and output capacitor; dual pins reduce IR drop and improve thermal dissipation.
PGND (Pin 8)	Power ground return	Low-impedance path for high-current switching loop; must be connected directly to ePAD and separated from AGND.
AGND (Pin 9)	Analog reference ground	Reference for error amplifier and bias circuitry; requires separate low-noise ground plane tied to PGND at single point.
VIN (Pin 10)	Input power supply	Accepts 2.7–5.5 V; requires ≥2.2 µF ceramic bypass capacitor placed adjacent to VIN and PGND.
ePAD	Thermal & electrical ground	Must be soldered to large copper pour tied to PGND; provides primary thermal path (θ_JA = 76°C/W).

Key Features

Feature	Design Value
Integrated inductor	0.36 µH embedded component eliminates external inductor, reducing BOM count to only two capacitors and saving >3 mm² board space.
HyperLight Load® mode	PFM operation below ~150 mA delivers 78% efficiency at 1 mA load-critical for standby power in handheld devices.
Ultra-fast transient response	Sub-10 µs recovery from 0–400 mA load steps (per Figure 2-26); maintains core voltage stability during CPU burst activity.
Low-output-voltage ripple	7 mV ripple in full PWM mode and 30 mV_PP in HyperLight Load® mode enable clean power for noise-sensitive RF and ADC subsystems.
Fully integrated MOSFETs	On-chip PMOS/NMOS switches with R_DS(ON) ≤ 0.8 Ω eliminate gate-drive complexity and external FET selection effort.

FAQ

What is the output voltage of the MIC33030-GYHJ-T5?

The MIC33030-GYHJ-T5 delivers a fixed 1.8 V output voltage with ±2.5% accuracy over temperature (–40°C to +125°C) and line/load conditions. This is factory-trimmed and requires no external feedback components-unlike adjustable variants such as MIC33030-AYHJ-T5 which use an FB pin and resistor divider.

Does the MIC33030-GYHJ-T5 require an external inductor?

No, the MIC33030-GYHJ-T5 integrates a 0.36 µH inductor internally, eliminating the need for any external magnetic component. The design requires only two external ceramic capacitors-one on VIN and one on VOUT-making it a true two-component solution beyond the IC itself.

What is the maximum junction temperature rating for the MIC33030-GYHJ-T5?

The MIC33030-GYHJ-T5 is rated for a junction temperature range of –40°C to +125°C. Thermal shutdown activates at 160°C (with 20°C hysteresis), and its 2.5 mm × 2.0 mm HJDFN package has a θ_JA of 76°C/W-enabling reliable operation in thermally demanding portable environments when properly mounted to a thermal pad.

How does HyperLight Load® mode improve efficiency in the MIC33030-GYHJ-T5?

HyperLight Load® mode enables pulse-frequency modulation (PFM) below ~150 mA load, reducing switching losses by only activating the regulator when needed. This achieves up to 78% efficiency at 1 mA load and 21 µA quiescent current-significantly extending battery life in standby or low-activity states compared to fixed-frequency PWM-only regulators.

Can the MIC33030-GYHJ-T5 be used with a 2.2 µF output capacitor?

Yes, the MIC33030-GYHJ-T5 is explicitly designed to be stable with a minimum 2.2 µF X5R/X7R ceramic output capacitor. Using this value meets all stability, ripple (<30 mV_PP), and transient response requirements per the datasheet-though larger values (e.g., 4.7 µF) further reduce ripple and improve load-step recovery.
