Product details

Overview

MP6907GJ-Z from Monolithic Power Systems is a fast turn-off flyback synchronous rectifier controller IC designed to replace Schottky diodes in high-efficiency AC/DC flyback converters. It regulates external MOSFET conduction to ~70mV forward drop, supports CCM/DCM/QR operation modes, features 25ns total turn-off delay, 4.2V–35V VDD range, and operates in SOIC8 or TSOT23-6 packages - enabling up to 1.5W power savings in notebook adapters.

For engineers reviewing the MP6907GJ-Z datasheet, MP6907GJ-Z pinout, MP6907GJ-Z application, or MP6907GJ-Z equivalent, this page delivers verified functional identity, validated pin roles for TSOT23-6, confirmed CCM/DCM/QR mode support, exact quiescent current (150μA light-load), and real-world timing thresholds (e.g., -15mV turn-off, 2.12V SYNC threshold) critical for secondary-side gate driver design and energy-efficient standby compliance.

Technical Context

The MP6907GJ-Z implements adaptive synchronous rectification by sensing V_D–V_SS voltage across an external MOSFET's body diode, triggering gate drive when V_DS falls below –70mV and disabling it at –15mV with 40–100ns total turn-off delay. Its control loop includes programmable light-load latch-off via LL pin (1.95μs pulse width at R_LL = 100kΩ) and thermal shutdown at 150°C with 10°C hysteresis.

It integrates a dedicated SYNC input that forces immediate gate disable upon >2.12V rising edge - essential for reliable CCM operation - and supports both high-side and low-side rectification topologies using auxiliary winding, secondary winding, or output-derived V_DD supply within 4.2V–35V range.

Key Specifications

Parameter	Value and Actual Design Meaning
VDD Range	4.2V to 35V - enables direct VDD derivation from 5V–24V outputs or auxiliary windings without LDO
Turn-off Threshold (VSS–VD)	–15mV typical - sets precise zero-current crossing detection for minimal reverse conduction loss
Total Turn-off Delay	40ns to 100ns - ensures sub-100ns MOSFET turn-off critical for QR/CCM stability at >300kHz
Light-load Quiescent Current	~150μA - meets Energy Star 1W standby requirements without sacrificing startup responsiveness
SYNC Threshold Voltage	2.12V typical - allows clean TTL/CMOS-level interface with primary-side controllers for CCM coordination
Thermal Shutdown	150°C with 10°C hysteresis - prevents MOSFET overstress during overload while enabling automatic recovery at 140°C
Forward Voltage Regulation	~70mV - reduces conduction loss to P_CON ≈ I_SD × 70mV, independent of MOSFET R_DS(ON)

Pinout & Package

MP6907GJ-Z is packaged in TSOT23-6 - a 2.9mm × 1.6mm surface-mount package with 0.95mm height and 0.65mm pitch, optimized for compact flyback secondary-side layouts.

Pin/Terminal	Circuit Role	Design Meaning
1 (PGND)	Power ground return	Low-inductance return path for gate driver sink current; must be tied to MOSFET source and kept separate from signal ground
2 (EN)	Enable input	Active-high logic control: pulls VG low when EN = 0V, reducing shutdown current to 105–200μA
3 (VD)	Drain voltage sense	High-voltage input (up to 180V) sensing MOSFET drain; requires <1kΩ series resistor to limit current during negative VGS
4 (VDD)	Supply voltage	Primary power input (4.2–35V); decoupled with ≥1µF ceramic capacitor placed adjacent to pin
5 (VSS)	Signal ground reference	Reference for VD, LL, and SYNC; must be connected to MOSFET source with minimal trace length to avoid noise coupling
6 (VG)	Gate driver output	Push-pull driver delivering 10–13V high-level and <0.1V low-level to control N-channel MOSFET gate

Key Features

Feature	Design Value
Fast turn-off propagation	15ns VD-triggered + 45ns SYNC-triggered delays ensure sub-60ns gate disable for QR/CCM reliability
Programmable light-load entry	LL pin sets 1.4–2.5μs conduction-time threshold via external resistor, enabling precise efficiency optimization at <10% load
CCM-compatible SYNC interface	2.12V threshold with 10–15μA internal pull-down allows direct connection to primary-side controller sync pins without level-shifting
Wide VDD operating range	4.2V–35V eliminates need for auxiliary LDO in most 5V–24V output designs, simplifying BOM and layout
High-side/low-side flexibility	Single IC supports both configurations via VSS grounding scheme - no topology-specific variants required

Applications

Use Scenario: DIN-rail mounted 24V/48V industrial power supplies operating continuously at 60°C ambient with strict thermal derating.

IC Role / Device Role / Timing Role: High-reliability flyback SR controller with 150°C thermal shutdown and 180V VD rating for robustness against line transients and transformer leakage spikes.

Use Value: Eliminates Schottky thermal runaway risk while maintaining <150μA quiescent current during brown-out conditions.

Medical Grade SMPS

Smart Home Power Supplies

Use Scenario: IEC 60601-1 compliant 12V/5A medical power supply requiring reinforced isolation and <0.5W no-load dissipation.

IC Role / Device Role / Timing Role: Isolated secondary-side gate driver with VSS-referenced sensing and PGND-separated power return to preserve creepage/clearance integrity.

Use Value: Achieves <0.3W no-load loss via light-load latch-off and 25ns turn-off, exceeding UL 62368-1 standby requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar flyback synchronous rectifier controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MP6908GJ-Z	Higher VDD UVLO (4.5V vs. 3.97V), 20ns faster turn-off (TDoff = 20ns typ.), adds VDD OVP clamp	Better suited for 36V+ auxiliary supplies and ultra-fast QR designs >500kHz	Select when primary-side controller supports tighter timing margins and higher VDD rails are available
SRK1001TR	Fixed 200ns turn-off delay, no SYNC input, 5V-only VDD range, integrated VDD LDO	Limited to low-voltage (<12V) outputs and DCM-only operation; no CCM coordination capability	Choose only for cost-sensitive, fixed-output, low-power (<15W) designs where CCM support is unnecessary

Compared with MP6907GJ-Z, MP6908GJ-Z offers superior timing precision and overvoltage protection for demanding QR/CCM hybrids, while SRK1001TR trades flexibility for integration simplicity in low-complexity DCM adapters - making MP6907GJ-Z the balanced choice for mid-power (15–90W), multi-mode flyback systems requiring standby compliance and topology agility.

FAQ

What is the maximum VD voltage rating for MP6907GJ-Z?

The MP6907GJ-Z supports VD to VSS up to +180V per absolute maximum ratings. This enables direct use with 100VAC–264VAC inputs in flyback topologies without external clamping, provided the external MOSFET's drain rating matches or exceeds this value and layout minimizes voltage overshoot.

How does the LL pin configure light-load behavior?

The LL pin sets the light-load conduction-time threshold using an external resistor: T_LL = 1.95μs × (100kΩ / R_LL). When MOSFET conduction duration falls below T_LL for longer than the enter delay, the IC latches off VG to reduce driver loss. Pulling LL low disables the gate driver entirely.

Can MP6907GJ-Z operate in high-side rectification configurations?

Yes - MP6907GJ-Z supports high-side rectification by connecting VSS to the MOSFET source (floating node) and referencing VD to that same point. The IC's VSS-referenced sensing architecture and PGND/VSS separation enable safe operation without level shifters or isolated supplies.

What is the purpose of the SYNC pin, and what voltage triggers it?

The SYNC pin provides external forced gate disable for CCM operation. A rising edge exceeding 2.12V (typical) immediately pulls VG low, overriding internal control. Internal 10–15μA pull-down ensures default low state when unconnected, preventing unintended activation.

Does MP6907GJ-Z require an external bootstrap capacitor?

No - MP6907GJ-Z uses a direct-drive gate output (VG) referenced to VSS, eliminating the need for bootstrap capacitors. Its push-pull driver delivers 10–13V high-side and <0.1V low-side levels directly, simplifying layout and improving reliability in high-side configurations.

How is thermal shutdown implemented and recovered?

Thermal shutdown activates at 150°C junction temperature, pulling VG low to halt switching. Recovery occurs automatically when junction temperature drops to 140°C due to 10°C hysteresis, restoring normal operation without external reset - ensuring robust protection during sustained overload or poor heatsinking.

What MOSFET RDS(ON) is recommended for a 5A output application?

For 5A output, MPS recommends R_DS(ON) ≥ 7mΩ to maintain V_DS ≈ –70mV during conduction. Lower R_DS(ON) causes premature turn-off as |I_SD × R_DS(ON)| exceeds 70mV, increasing switching loss - balancing conduction efficiency and gate drive stability.
