Product details

Overview

MIC33030-JYHJ-TR from Microchip Technology is a 2.5 V fixed-output, 400 mA synchronous buck regulator with integrated inductor and HyperLight Load® mode, operating from 2.7 V to 5.5 V input, delivering ±2.5% output voltage accuracy over temperature, and housed in a 2.5 mm × 2.0 mm 10-lead HJDFN package for space-constrained portable power applications.

For engineers reviewing the MIC33030-JYHJ-TR datasheet, MIC33030-JYHJ-TR pinout, MIC33030-JYHJ-TR application, or MIC33030-JYHJ-TR equivalent, key selection considerations include its internal inductor architecture, 21 µA quiescent current in HyperLight Load® mode, 8 MHz PWM operation, ultra-fast transient response, and compatibility with minimal external components (two capacitors only).

Technical Context

The MIC33030-JYHJ-TR implements a proprietary HyperLight Load® control scheme combining minimum on-time/off-time pulse frequency modulation (PFM) at light loads and fixed-frequency 8 MHz PWM in continuous conduction mode above ~150 mA. It integrates both high-side PMOS and low-side NMOS switches with typical R_DS(ON) of 0.65 Ω (PMOS) and 0.8 Ω (NMOS), enabling asynchronous rectification and eliminating external diode requirements.

This device uses a single-point SNS feedback connection for fixed-output variants (no FB pin), supports undervoltage lockout (2.45–2.65 V turn-on threshold), and features thermal shutdown (160°C) with 20°C hysteresis, current-limit protection (0.41–1 A), and soft-start (100 µs). Its analog ground (AGND) and power ground (PGND) separation ensures noise immunity in mixed-signal environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.7 V to 5.5 V - supports single-cell Li-ion, USB, and regulated 3.3 V/5 V rails without external pre-regulation.
Output Voltage	Fixed 2.5 V ±2.5% - eliminates external resistor divider, simplifies layout and reduces BOM count.
Max Output Current	400 mA - sufficient for powering processor cores, RF modules, and sensor subsystems in portable devices.
Quiescent Current	21 µA typical - enables >1000-hour battery life in always-on low-power states (e.g., GPS standby, Bluetooth LE advertising).
Switching Frequency	Up to 8 MHz - allows use of tiny 2.2 µF ceramic output capacitors and minimizes EMI filter size.
Output Ripple	7 mV_PP in full PWM mode - meets tight noise requirements for ADC references and RF power amplifiers.
Junction Temp Range	–40°C to +125°C - qualified for automotive infotainment, industrial handhelds, and extended-temperature embedded systems.
Shutdown Current	0.01 µA - enables true zero-power sleep modes when EN is asserted low.

Pinout & Package

Package: 10-lead 2.5 mm × 2.0 mm × 1.15 mm HJDFN with exposed thermal pad (ePAD), RoHS-compliant, Pb-free matte tin finish.

Pin/Terminal	Circuit Role	Design Meaning
SNS (Pin 1)	Sense Input	Direct connection to VOUT near output capacitor; provides precision feedback for regulation without external resistors.
NC (Pin 2)	No Connect	Internally unconnected; must be left floating or tied to AGND/PGND per layout best practice - no electrical function.
EN (Pin 3)	Enable Control	Logic-high (>0.9 V) enables regulation; logic-low (<0.5 V) shuts down IC, reducing supply current to 0.01 µA.
SW (Pins 4,5)	Internal Switch Node	Connection to internal inductor; not routed externally - eliminates PCB trace inductance and EMI concerns.
VOUT (Pins 6,7)	Regulated Output	Delivers 2.5 V to load; requires ≥2.2 µF ceramic capacitor placed adjacent to pin for stability and ripple suppression.
PGND (Pin 8)	Power Ground	High-current return path for switching loop; must be connected to ePAD and kept separate from AGND to avoid noise coupling.
AGND (Pin 9)	Analog Ground	Reference ground for error amplifier and bias circuitry; connects to PGND at single point near ePAD.
VIN (Pin 10)	Input Supply	Accepts 2.7–5.5 V; requires ≥2.2 µF ceramic bypass capacitor placed between VIN and PGND, close to the pin.
ePAD	Thermal & Electrical Pad	Must be soldered to solid PGND copper pour for thermal dissipation (θ_JA = 76°C/W) and EMI reduction.

Key Features

Feature	Design Value
Integrated Inductor	Eliminates external inductor placement, reduces solution footprint by >40%, and removes inductor selection, saturation, and EMI shielding design effort.
HyperLight Load® Mode	Delivers 78% efficiency at 1 mA load while maintaining ultra-fast transient response - ideal for burst-mode processors and intermittent-sensing IoT nodes.
Ultra-Low Output Ripple	7 mV_PP in PWM mode and 30 mV_PP in HyperLight Load® mode - avoids need for additional LC filtering in noise-sensitive analog or RF signal chains.
Single-Capacitor Output Stability	Stable with ≥2.2 µF X5R/X7R ceramic capacitor - enables use of low-cost, small-footprint 0603 or 0402 capacitors without compensation network.
Thermal & Current Protection	Includes foldback current limit (0.41–1 A), thermal shutdown (160°C), and 100 µs soft-start - prevents inrush damage and ensures robust operation under fault conditions.
Small 2.5 mm × 2.0 mm Package	Reduces total DC/DC solution area to <12 mm² including two capacitors - fits within tight board real estate constraints of wearables and compact modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar buck regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MIC33030-GYHJ-TR	Fixed 1.8 V output; identical package, pinout, and performance specs except VOUT.	Used where lower core voltage required (e.g., ARM Cortex-M0+ MCUs, low-voltage sensors).	Select when target load requires 1.8 V instead of 2.5 V - same layout, no redesign needed.
MIC33030-4YHJ-TR	Fixed 1.2 V output; shares all electrical characteristics, thermal behavior, and package dimensions.	Targeted at ultra-low-voltage digital logic (e.g., FPGA I/O banks, LPDDR2 termination, SoC auxiliary rails).	Choose for 1.2 V systems - drop-in replacement with identical footprint and thermal profile.

Compared with MIC33030-GYHJ-TR and MIC33030-4YHJ-TR, the MIC33030-JYHJ-TR provides optimal headroom for 2.5 V analog interfaces (e.g., camera ISPs, audio codecs) while maintaining higher efficiency than 1.2 V/1.8 V variants at mid-load currents (100–300 mA), making it preferred for mixed-signal portable subsystems.

FAQ

What is the output voltage of the MIC33030-JYHJ-TR?

The MIC33030-JYHJ-TR is a fixed-output buck regulator with a nominal output voltage of 2.5 V, specified with ±2.5% accuracy over temperature and load. This value is laser-trimmed at wafer test and does not require external feedback resistors - the SNS pin connects directly to VOUT for regulation. The MIC33030-JYHJ-TR maintains this voltage across its full 2.7–5.5 V input range and 0–400 mA load range.

Does the MIC33030-JYHJ-TR require an external inductor?

No, the MIC33030-JYHJ-TR integrates the power inductor internally, eliminating the need for any external magnetic component. This architecture reduces total solution size, removes inductor selection variables (saturation current, DCR, shielding), and improves EMI performance by containing the high-di/dt switching node within the package. The SW pins connect directly to the internal inductor and are not intended for external routing in standard designs.

What is the purpose of the NC pin on the MIC33030-JYHJ-TR?

Pin 2 of the MIC33030-JYHJ-TR is marked NC (No Connect) and is not internally connected to any circuitry. It may be left floating or tied to AGND/PGND per PCB layout best practices for mechanical stability and thermal relief - but it serves no electrical function. This pin is present for package compatibility across the MIC33030 family (e.g., adjustable variants use Pin 2 as FB), and its presence does not affect MIC33030-JYHJ-TR operation.

How does HyperLight Load® mode improve efficiency in the MIC33030-JYHJ-TR?

HyperLight Load® mode in the MIC33030-JYHJ-TR uses pulse frequency modulation (PFM) with variable off-time to deliver energy only when needed, reducing switching losses at light loads. This achieves 78% efficiency at 1 mA output current while maintaining 21 µA quiescent current. Unlike conventional PFM controllers, it preserves ultra-fast transient response (<10 µs recovery from 0→150 mA step) - a key advantage for MIC33030-JYHJ-TR in burst-mode applications like GPS acquisition or sensor wake-up cycles.

Can the MIC33030-JYHJ-TR be used with a 2.2 µF output capacitor?

Yes, the MIC33030-JYHJ-TR is specifically designed to be stable with a minimum 2.2 µF X5R or X7R ceramic output capacitor, as confirmed in Section 5.3 (Compensation) and Figure 5-1 of the datasheet. Using this value meets all stability criteria across temperature and load, delivers the specified 7 mV_PP ripple in PWM mode, and enables compact 0603/0402 footprints. Larger capacitors further reduce ripple and improve transient response but are not required for basic functionality of the MIC33030-JYHJ-TR.
