Product details
Overview
MP6907GS-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 adapters and flyback converters. It regulates external MOSFET conduction to ~70mV forward drop, delivers 25ns total turn-off delay, supports CCM/DCM/QR modes, and operates across 4.2V–35V VDD - enabling use in notebook adapters, industrial power supplies, and battery-powered systems.
For engineers reviewing the MP6907GS-Z datasheet, MP6907GS-Z pinout, MP6907GS-Z application, or MP6907GS-Z equivalent, key selection criteria include its light-load sleep mode (~150μA), SYNC-controlled CCM reliability, dual-package availability (SOIC8/TSOT23-6), and support for both high-side and low-side rectification topologies.
Technical Context
The MP6907GS-Z implements adaptive gate control using VD–VSS sensing to maintain ~70mV synchronous MOSFET conduction voltage, with programmable turn-on blanking (~1.6μs) and turn-off blanking (160ns). Its control logic dynamically adjusts VG based on real-time VDS feedback to minimize conduction loss while preventing shoot-through.
It integrates dedicated circuitry for CCM operation via the SYNC input (2.12V threshold), light-load latch-off triggered by LL resistor timing (TLL = 1.95μs × RLL/100kΩ), and thermal shutdown at 150°C with 10°C hysteresis - all operating within a -40°C to +125°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 4.2V to 35V - powers IC directly from output or auxiliary winding without external LDO in most flyback designs |
| Forward Voltage Regulation | ~70mV - sets MOSFET conduction voltage to minimize PCON ≈ ISD × 70mV, decoupling loss from RDS(ON) |
| Turn-Off Total Delay | 40–100ns - enables reliable zero-current switching in QR/DCM and prevents reverse conduction in CCM |
| Light-Load Quiescent Current | ~150μA - meets Energy Star 1W standby requirements by latching off gate driver during low-conduction periods |
| SYNC Threshold Voltage | 2.12V (typ) - allows direct interface with PWM controller sync outputs for deterministic CCM gate disable |
| Thermal Shutdown | 150°C with 10°C hysteresis - protects against sustained overload without requiring external thermal monitoring |
| VD Sense Range | -1V to +180V - supports high-voltage secondary-side sensing in universal-input offline converters |
Pinout & Package
MP6907GS-Z is supplied in SOIC8 package (JEDEC MS-012), with exposed PGND pad for thermal performance. Pin functions are validated per MPS Rev. 1.02 datasheet and match physical layout in typical application circuits.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PGND) | Power ground return | Low-inductance return path for gate driver current; must be connected to MOSFET source and PCB ground plane |
| 2 (EN) | Enable input | Active-high digital control: pulls VG low when EN = 0V, reducing shutdown current to 105–200μA |
| 3 (LL) | Light-load timing | Resistor-programmable entry/exit delay for sleep mode; internal ~2V bias sets TLL = 1.95μs × RLL/100kΩ |
| 4 (VD) | Drain voltage sense | High-voltage input (up to +180V) sensing MOSFET drain; requires Kelvin connection near FET for noise immunity |
| 5 (VSS) | Signal ground reference | Reference for VD, VG, and internal comparators; separate from PGND to avoid ground bounce coupling |
| 6 (VDD) | Supply voltage | 4.2–35V input powering internal logic and gate driver; bypassed with ≥1μF ceramic capacitor to PGND |
| 7 (SYNC) | External turn-off control | Rising-edge-triggered shutdown: >2.12V disables VG immediately, critical for stable CCM operation |
| 8 (VG) | Gate driver output | 11.7V (typ) high-drive capable of sinking 0.5A; drives N-channel MOSFET gate with <80ns turn-off delay into 4.7nF load |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive VDS-regulated conduction | Maintains ~70mV forward drop regardless of MOSFET RDS(ON), eliminating need for ultra-low-RDS(ON) devices |
| Programmable light-load sleep mode | Reduces system standby power by latching off VG when conduction period falls below TLL + TLL-H |
| SYNC-controlled CCM operation | Enables deterministic gate disable synchronized to primary-side controller, preventing cross-conduction in continuous mode |
| High-side and low-side compatibility | Supports both topologies via VD/VSS sensing architecture and independent PGND/VSS separation |
| Fast 25ns turn-off total delay | Minimizes reverse recovery losses in QR/DCM and ensures clean zero-current turn-off in high-frequency designs |
Applications
| Laptop AC/DC Adapters | Industrial Flyback PSUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous rectifier controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NCP4306DR2G | Fixed 60mV Vfwd regulation; no SYNC input; only SOIC8 package; higher 300μA light-load current | Lacks CCM synchronization capability; unsuitable for high-power CCM-dominant designs requiring precise turn-off timing | Select when cost sensitivity outweighs CCM robustness needs and standby current >150μA is acceptable |
| Vishay SiHP2110BD | Integrated MOSFET + controller in PowerPAK SO-8; fixed 75mV regulation; no LL or SYNC pins; 12V max VDD | Monolithic solution eliminates external FET but restricts VDD range and disables programmable sleep mode | Select for space-constrained DCM-only adapters where auxiliary supply design complexity must be minimized |

FAQ
What is the function of the LL pin on MP6907GS-Z?
The LL pin sets light-load sleep mode timing via an external resistor. When the synchronous MOSFET conduction period remains below TLL for longer than the programmed enter delay, the IC latches off VG to reduce quiescent current to ~150μA. Leaving LL open disables sleep mode; pulling LL low forces immediate gate disable.
Can MP6907GS-Z operate in high-side rectification configurations?
Yes - MP6907GS-Z supports high-side rectification using its differential VD–VSS sensing architecture. The IC references VSS to the MOSFET source, allowing accurate VDS monitoring regardless of whether the FET is placed between transformer secondary and output rail (low-side) or between transformer and ground (high-side).
What is the maximum VD voltage rating for MP6907GS-Z?
The absolute maximum VD-to-VSS rating is +180V, verified per MPS Rev. 1.02 datasheet. This enables safe operation in universal-input offline flyback converters where reflected voltages can exceed 150V during line surges or no-load transients.
How does the SYNC pin improve CCM operation reliability?
The SYNC pin accepts a rising-edge signal (>2.12V) from the primary-side controller to force immediate VG shutdown. This prevents cross-conduction during CCM overlap intervals and eliminates reliance on VDS zero-crossing detection, which can be unreliable under heavy loads or parasitic ringing.
Is MP6907GS-Z compatible with 5V logic-level MOSFETs?
Yes - MP6907GS-Z's VG output delivers 11.7V (typ) when VDD >10V and supports both 5V and 12V logic-level N-channel MOSFETs. Its gate driver sinks 0.5A and features low pull-down impedance (0.8–1.6Ω), ensuring fast turn-off even with high-Qg FETs.
What thermal protection mechanisms does MP6907GS-Z include?
MP6907GS-Z incorporates junction temperature monitoring with thermal shutdown at 150°C and automatic recovery at 140°C (10°C hysteresis). This protection is internal and does not require external components, safeguarding the IC and external MOSFET during sustained overload or poor heatsinking conditions.
Does MP6907GS-Z require a minimum load to regulate properly?
No - MP6907GS-Z operates down to zero load via its light-load sleep mode. When conduction time drops below the LL-programmed threshold, VG is latched off, reducing ICC to ~150μA. This eliminates minimum load requirements common in older SR controllers.
