Product details

Overview

MP6922AGS-Z from Monolithic Power Systems is a dual-channel, fast-turn-off intelligent rectifier IC designed for synchronous rectification in LLC resonant converters. It drives two N-channel MOSFETs, regulates forward voltage drop to 30mV, achieves 20ns total turn-off delay, supports up to 300kHz switching, and includes reverse-current protection and light-load latching for <600μA quiescent current - deployed in AC-DC adapters and LCD TV power supplies.

For engineers reviewing the MP6922AGS-Z datasheet, MP6922AGS-Z pinout, MP6922AGS-Z application, or MP6922AGS-Z equivalent, key selection criteria include V_DS regulation accuracy (±15mV), SOIC14 package thermal resistance (θ_JA = 86°C/W), dual-channel independent sensing (VD1/VS1 & VD2/VS2), and compatibility with both standard and logic-level MOSFETs in CCM/CrCM/DCM operation.

Technical Context

The MP6922AGS-Z implements adaptive gate control using dual high-voltage drain-sense inputs (VD1/VD2) referenced to dedicated source pins (VS1/VS2) and common VSS, enabling independent channel operation in center-tapped or full-wave LLC topologies. Its blanking logic enforces 1μs minimum ON-time and dynamically adjusts turn-off threshold from +30mV to +100mV during turn-on transients to suppress ringing-induced false triggering.

Reverse-current protection operates via RCP pin monitoring: when voltage across an external divider exceeds VRCP (3V typ), the IC latches both gate drivers for 150μs (τ_RCP) to prevent shoot-through during high-frequency CCM reversal. Light-load mode activates when MOSFET conduction period falls below 2.2μs, initiating 160μs entry delay before latching VG1/VG2 - configurable via external LL pin resistor in SOIC14.

Key Specifications

Turn-Off Total Delay	75ns max (C_LOAD=10nF); enables reliable zero-current switching in high-frequency LLC converters up to 300kHz.
Reverse-Current Threshold	3V on RCP pin; triggers 150μs driver latch to block shoot-through during body-diode reverse recovery in CCM.
Light-Load Quiescent Current	<600μA; achieved by latching gate drivers under low conduction duty, meeting Energy Star 0.5W standby requirements.
V_DD Operating Range	8V to 24V; powers internal circuitry directly from auxiliary winding output, eliminating need for separate bias supply.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MP6922AGN-Z	SOIC8E package with exposed thermal pad (θ_JA = 50°C/W); same electrical specs but higher thermal performance and smaller footprint.	Better suited for space-constrained adapters where board area is limited and thermal management relies on PCB copper.	Select when thermal budget is tighter than 1.5W and layout allows SOIC8E land pattern with thermal vias.
SRK2001A	Single-channel controller with external V_DS comparator; lacks integrated RCP and programmable light-load timing; requires external components for dual operation.	Requires two ICs and additional passive components to match MP6922AGS-Z's dual-channel integration and protection features.	Choose only if legacy design uses SRK2001A and dual-channel consolidation is not required.

Compared with MP6922AGN-Z, MP6922AGS-Z offers lower pin count density and higher package thermal resistance but enables simpler routing in multi-layer boards with dedicated ground planes; versus SRK2001A, it eliminates component count, improves reliability through integrated protection, and reduces BOM cost by 35% in dual-channel implementations.

FAQ

What is the maximum allowable V_DS transient voltage the MP6922AGS-Z can withstand on VD1/VD2 pins?

The MP6922AGS-Z supports up to +180V on VD1 and VD2 pins under transient conditions, as specified in Absolute Maximum Ratings. This rating applies to short-duration spikes (e.g., LLC resonance overshoot), not continuous DC stress. External series resistors are recommended between VDx and MOSFET drain to limit current during negative gate excursions below –0.7V.

How does the light-load latching function interact with burst-mode operation in LLC converters?

During burst mode, the MP6922AGS-Z monitors MOSFET OFF period width; if it exceeds τ_LL-OFF (50μs), the IC enters light-load mode and latches VG1/VG2. It exits latching when V_DS drops below –30mV, ensuring immediate resumption of synchronous rectification at burst onset - critical for maintaining tight output regulation during dynamic load steps.

Can the MP6922AGS-Z drive logic-level MOSFETs with V_GS(th) as low as 1.0V?

Yes - the MP6922AGS-Z delivers gate drive up to 14.5V (VDD >16V) and supports logic-level MOSFETs via its adaptive regulation loop. Its turn-on threshold is –30mV on V_DS, and the gate driver maintains sufficient V_GS headroom even at low V_DD (8V), ensuring robust enhancement of MOSFETs with 1.0V threshold voltage across –40°C to +125°C.

Is the RCP pin mandatory for reverse-current protection in all applications?

No - RCP is optional. If unused, reverse-current protection is disabled and the pin must be left open or tied to VDD via a 10kΩ resistor per datasheet guidance. In full-wave center-tapped LLC topologies operating above 200kHz in CCM, however, RCP connection is strongly recommended to prevent shoot-through during rapid current reversal.

What is the purpose of the VSS pin, and how should it be connected in a dual-MOSFET layout?

VSS serves as the common source reference for both channels' sensing circuitry. It must be connected to the shared source node of the two synchronous rectifier MOSFETs - not to PGND - to ensure accurate differential V_DS measurement. Layout best practice requires short, low-inductance traces from VS1 and VS2 to VSS, avoiding shared return paths with high di/dt gate drive currents.

Does the MP6922AGS-Z support CrCM (critical conduction mode) operation, and how is it implemented?

Yes - the MP6922AGS-Z natively supports CrCM by detecting zero-current crossing via V_DS polarity reversal. When V_DS goes negative (<–500mV), the IC initiates turn-on after ~200ns delay; blanking logic then enforces 1μs minimum ON-time. This behavior ensures clean transitions at boundary conduction, eliminating audible noise and improving light-load efficiency without external mode detection circuitry.
