Product details

Overview

MB39C007WQN-G-JN-ERE1 from Cypress Semiconductor is a dual-channel, current-mode synchronous buck DC/DC converter IC with integrated P-ch (0.3 Ω typ) and N-ch (0.2 Ω typ) MOSFETs, 2.0 MHz fixed-frequency PWM/PFM operation, 1.30 V reference voltage, and built-in voltage detection (XPOR). It delivers up to 800 mA per channel from 2.5–5.5 V input, achieving 96% peak efficiency-ideal for powering core logic and I/O rails in mobile phones and portable HDDs.

For engineers reviewing the MB39C007WQN-G-JN-ERE1 datasheet, MB39C007WQN-G-JN-ERE1 pinout, MB39C007WQN-G-JN-ERE1 application, or MB39C007WQN-G-JN-ERE1 equivalent, this device supports fast transient response, low shutdown current (≤1 µA), and no external flyback diode requirement-key selection criteria for space-constrained, battery-powered systems.

Technical Context

The MB39C007 operates in current-mode control, using peak inductor current sensing (via I-V conversion of LX node current) to regulate output voltage-enabling inherent cycle-by-cycle current limiting and improved load step response. Its PFM/PWM hybrid mode automatically transitions between fixed-frequency PWM (full load) and pulse-frequency modulation (light load), maintaining high efficiency across 0.1–100% load range.

Integrated blocks include a 1.30 V ±2% bandgap reference, XPOR voltage detector with 0.6 V threshold, over-temperature protection (trip at 135°C, recovery at 110°C), and independent CTL1/CTL2 enable inputs for per-channel power sequencing. The error amplifier includes internal phase compensation, eliminating need for external compensation components.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.5 V to 5.5 V - supports single-cell Li-ion and USB-powered systems without pre-regulation.
Output Current per Channel	800 mA max - sufficient to power ARM Cortex-M cores, NAND flash I/O, or camera sensor interfaces.
Switching Frequency	2.0 MHz typical - enables use of small 1–2.2 µH inductors and reduces EMI filtering footprint.
Peak Efficiency	96% - minimizes thermal rise in QFN-24 package during sustained 500 mA loads.
Reference Voltage	1.30 V ±2% - sets output voltage via external resistor divider (e.g., 1.8 V, 2.5 V, 3.3 V).
Shutdown Current	≤1 µA - preserves battery life in standby modes of handheld devices.
R_DS(on) High-Side	0.3 Ω typical - limits conduction loss at 800 mA (≈192 mW dissipation per channel).
XPOR Threshold	0.6 V - triggers reset signal when monitored supply falls below safe operating level.

Pinout & Package

Packaged in a thermally enhanced 4×4 mm QFN-24 (WNN024) with exposed thermal pad, the MB39C007WQN-G-JN-ERE1 uses a dual-channel layout with separate power grounds (AGND/DGND1/DGND2), drive supplies (AVDD/DVDD1/DVDD2), and dedicated LX, OUT, MODE, and CTL pins per channel.

Pin/Terminal	Circuit Role	Design Meaning
1 CTLP	Voltage detection control	Disables XPOR monitoring when pulled low; enables full voltage supervision on VDET pin.
2,3 CTL1, CTL2	Channel enable inputs	Active-high logic controls independent startup/shutdown of CH1 and CH2 converters.
4 AGND	Analog ground	Reference return for error amp, reference, and voltage detection circuits-must be star-connected to minimize noise coupling.
5 AVDD	Analog supply	Power source for control circuitry; requires local 1 µF ceramic decoupling to AGND.
6 VREF	Reference output	Provides stable 1.30 V for external feedback dividers; not intended to source load current.
7 VDET	Voltage monitor input	Monitors system supply (e.g., main battery); 0.6 V threshold triggers XPOR open-drain output.
8,23 VREFIN1,VREFIN2	Error amp non-inv inputs	Connect to resistor dividers from OUT1/OUT2 to set regulated output voltages independently.
9,22 MODE1,MODE2	Operation mode select	Ground = PFM/PWM auto-switching; open = forced PWM for constant frequency EMI control.
10,21 OUT1,OUT2	Feedback sense nodes	High-impedance inputs tied to resistor dividers; used with VREF to close regulation loop.
11,12,19,20 DVDD1,DVDD2	Driver supply	Power for gate drivers; must be ≥VOUT + 1 V to ensure full N-ch FET enhancement.
13,18 LX1,LX2	Switch node outputs	Connect to external inductors; high-impedance during shutdown to prevent backfeed.
14,15,16,17 DGND1,DGND2	Driver ground	Return path for switching currents; must be isolated from AGND except at single-point connection.
24 XPOR	Open-drain reset output	Pulled high externally to generate system reset when VDET < 0.6 V; sinks >1 mA.

Key Features

Feature	Design Value
Integrated synchronous rectification	Eliminates external Schottky diodes-reducing BOM count and PCB area while improving light-load efficiency.
Current-mode control architecture	Enables inherent overcurrent protection and stable operation with minimal output capacitance (≥10 µF ceramic).
Internal phase compensation	Removes need for external compensation network-simplifying design and reducing layout sensitivity.
Independent channel enable and mode control	Supports staggered startup, dynamic voltage scaling, and selective power gating in multi-rail systems.
Thermal shutdown with hysteresis	Shuts down at 135°C junction temperature and recovers at 110°C-preventing thermal runaway without external sensors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel synchronous buck converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Texas Instruments TPS6223x	Single-channel, 3 MHz switching, 600 mA max; lacks XPOR and independent MODE pins.	Suitable only for single-rail systems; requires external reset IC for voltage monitoring.	Select when board space is critical and dual-channel operation is unnecessary.
Rohm BD9A100MUV	2.5 MHz, 1 A per channel, integrated soft-start; no built-in voltage detector or XPOR output.	Requires external POR circuit; better suited for automotive-grade thermal performance (−40°C to +125°C).	Prefer for higher output current or extended temperature range-accept added component count for supervision.

Compared with TPS6223x and BD9A100MUV, the MB39C007WQN-G-JN-ERE1 uniquely integrates voltage detection with open-drain XPOR output and per-channel PFM/PWM mode control-enabling self-contained power sequencing and reset generation in portable consumer designs without auxiliary ICs.

FAQ

What is the recommended inductor value for MB39C007WQN-G-JN-ERE1 at 2.0 MHz operation?

A 1.5 µH shielded power inductor with saturation current ≥1.2 A and DCR ≤80 mΩ is recommended. This value balances ripple current (≈30% of IOUT), efficiency, and physical size for typical 3.7 V input to 1.8 V/800 mA output. Inductor selection must also consider thermal derating at 85°C ambient.

Can MB39C007WQN-G-JN-ERE1 operate with only one channel enabled?

Yes. CTL1 and CTL2 are independent enable inputs-driving CTL2 low disables CH2 while CH1 remains fully operational. Both channels share AVDD, AGND, and VREF but have separate LX, OUT, MODE, and DVDD pins, allowing true single-channel operation without cross-talk or efficiency penalty.

How does the XPOR function interface with an external microcontroller?

XPOR is an open-drain output requiring an external pull-up resistor (typically 10–100 kΩ) to a logic-compatible voltage (e.g., 1.8 V or 3.3 V). When VDET drops below 0.6 V, XPOR pulls low to assert reset; microcontroller GPIO must be configured as interrupt-capable input with internal or external pull-up to detect the falling edge.

Is external phase compensation required for stability?

No. The MB39C007WQN-G-JN-ERE1 integrates a fully compensated error amplifier optimized for standard ceramic output capacitors (10–47 µF, ESR < 10 mΩ). No external compensation components are needed-verified across input range (2.5–5.5 V), output voltages (1.2–3.3 V), and load conditions (10–800 mA).
