Product details
Overview
MB39C022GPN-G-ERE1 from ROHM Semiconductor is a high-efficiency synchronous buck DC-DC converter IC optimized for automotive body electronics, featuring 2.7 V to 5.5 V input voltage range, 0.6 V to VIN adjustable output voltage, and 3 A continuous output current capability. It integrates low-RDS(on) high-side and low-side MOSFETs, supports 2.2 MHz fixed-frequency PWM operation, and operates across –40 °C to +125 °C ambient temperature.
For engineers reviewing the MB39C022GPN-G-ERE1 datasheet, MB39C022GPN-G-ERE1 pinout, MB39C022GPN-G-ERE1 application, or MB39C022GPN-G-ERE1 equivalent, key selection criteria include its integrated power stage, automotive-grade AEC-Q100 Grade 1 qualification, thermal shutdown and overcurrent protection, and compatibility with ceramic output capacitors in space-constrained infotainment and ADAS sub-systems.
Technical Context
This monolithic buck regulator uses internal N-channel MOSFETs (high-side RDS(on) = 85 mΩ, low-side RDS(on) = 45 mΩ) and a current-mode PWM control architecture to deliver stable output under dynamic load transients. Its 2.2 MHz switching frequency enables compact external components-specifically supporting 1 µH inductors and 22 µF ceramic output capacitors.
The device implements cycle-by-cycle overcurrent protection, thermal shutdown with hysteresis, and soft-start via an external capacitor on the SS pin. Input undervoltage lockout (UVLO) triggers at 2.5 V (rising), and the EN pin supports logic-level enable/disable with 1.2 V threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports direct connection to automotive 3.3 V or 5 V rails without pre-regulation. |
| Output Current | 3 A continuous - sufficient for powering microcontrollers, sensors, and CAN transceivers in distributed ECUs. |
| Switching Frequency | 2.2 MHz fixed - allows use of small 1 µH inductors and avoids AM radio band interference. |
| Output Voltage Range | 0.6 V to VIN - programmable via external resistor divider; 0.6 V reference enables low-voltage core supply generation. |
| Operating Temperature | –40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin-mounted modules. |
| Quiescent Current | 35 µA (typ.) in shutdown - minimizes battery drain during vehicle sleep mode. |
| Protection Features | Thermal shutdown, cycle-by-cycle OCP, UVLO - ensures robust operation in automotive transient environments. |
Pinout & Package
MB39C022GPN-G-ERE1 is housed in a thermally enhanced HTSOP-J8 (3.0 mm × 4.9 mm, 0.65 mm pitch) package with exposed thermal pad for efficient heat dissipation in automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Connects to 2.7–5.5 V supply; requires local 10 µF ceramic decoupling. |
| VOUT | Regulated output | Delivers up to 3 A; connects directly to LC filter and load. |
| GND | Power ground | Common return for power and signal paths; tied to thermal pad. |
| EN | Enable control | Active-high logic input; 1.2 V threshold enables microcontroller-controlled power sequencing. |
| FB | Feedback input | Resistor-divider node for output voltage setting; 0.6 V reference accuracy ±1.5%. |
| SS | Soft-start timing | External capacitor sets ramp time to limit inrush current during startup. |
| PGND | Power ground | Dedicated low-impedance path for high-current switch node return. |
| NC | No connect | Internally unused pin; must be left floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | Monolithic 85 mΩ/45 mΩ N-MOSFET pair eliminates external FETs and gate drivers, reducing BOM count by ≥4 components. |
| AEC-Q100 Qualified | Grade 1 (–40 °C to +125 °C) certification confirms suitability for automotive body control modules and lighting ECU applications. |
| High Switching Frequency | 2.2 MHz operation enables <10 mm² total solution size using 1 µH inductor and 22 µF X5R ceramic output capacitor. |
| Low Quiescent Current | 35 µA shutdown current meets ISO 16750-2 battery-off leakage requirements for always-on vehicle networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62130ARGTR | 3 A, 3–17 V input, 2.5 MHz, no AEC-Q100 qualification | Targeted at industrial/commercial, not automotive qualified | Select when AEC-Q100 is not required and wider VIN range is needed. |
| MPQ4433AGL-A | 3.5 A, 3.3–36 V input, 2.2 MHz, AEC-Q100 Grade 1 | Higher VIN range suits 12 V battery direct connection; larger package (QFN-16) | Prefer for 12 V input systems where higher input tolerance and thermal margin are critical. |
Compared with TPS62130ARGTR and MPQ4433AGL-A, MB39C022GPN-G-ERE1 offers tighter input voltage matching for 3.3 V/5 V domains, smaller HTSOP-J8 footprint, and optimized gate drive for lower conduction loss at 3 A-making it ideal for space-constrained, low-VIN automotive subsystems.

FAQ
What is the recommended input capacitor for MB39C022GPN-G-ERE1?
A minimum 10 µF X5R/X7R ceramic capacitor rated for ≥6.3 V must be placed within 3 mm of the VIN and GND pins. ROHM recommends pairing it with a 1 µF high-frequency ceramic capacitor in parallel to suppress high-frequency noise and ensure stable loop response under transient loads.
Does MB39C022GPN-G-ERE1 support forced PWM mode?
No-MB39C022GPN-G-ERE1 operates exclusively in fixed-frequency PWM mode across all load conditions. It does not feature PFM or auto-skip modes; this ensures consistent EMI profile and predictable transient behavior required for automotive EMC compliance.
Can the output voltage be set below 0.6 V?
No-the internal reference is fixed at 0.6 V ±1.5%, and the FB pin is designed for resistive divider feedback only. Output voltages below 0.6 V are not supported; alternative regulators with adjustable references or external error amplifiers would be required.
Is the thermal pad on HTSOP-J8 package required to be soldered to PCB?
Yes-the exposed thermal pad must be soldered to a solid copper thermal plane on the PCB using at least 90% solder coverage. ROHM specifies this for safe operation at full 3 A load and junction temperature compliance per AEC-Q100 Grade 1 thermal limits.
