CCM/DCM Flyback Ideal Diode with Integrated 100V/10mΩ MOSFET and No Need for Auxiliary Winding MP9989 Rev. 1.1 www.MonolithicPower.com 1 8/27/2020 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2020 MPS. All Rights Reserved.
DESCRIPTION
The MP9989 is a fast turn-off, intelligent rectifier for flyback converters that integrates a 100V MOSFET. It can replace a diode rectifier for higher efficiency and power density . The chip regulates the forward voltage drop of the internal power switch to 40mV(1) and turns off before the drain-source voltage reverses. The MP9989 can generate its own supply voltage without the need for auxiliary winding, which makes it suitable for charger applications with a low output voltage requirement or any other adaptor applications with high-side set-up. The internal ringing detection circuitry prevents the MP9989 from falsely turning on during discontinuous conduction mode (DCM) or quasi- resonant operations. The MP9989 is available in SOIC-8 and QFN4x5-8 packages.
FEATURES
Integrated 100V/10mΩ MOSFET Wide Output Range down to 0V No Need for Auxiliary Winding for High-Side or Low-Side Rectification Ringing Detection Prevents False Turn-On during DCM Operations Compatible with Energy Star 110µA Quiescent Current Supports DCM, CCM, and Quasi-Resonant Operations Available in SOIC-8 and QFN4x5-8 Packages

VDD is the supply of the MP9989. 2 2 SENSE MOSFET drain voltage sensing. SENSE is also used as the linear regulator input. 3, 4 3, 4 VS MOSFET source. VS is also used as a reference for VDD. 5, 6, 7, 8 5, 6, 7, 8 VD MOSFET drain. ABSOLUTE MAXIMUM RATINGS (2) Continuous drain current (TC = 25°C) Continuous drain current (TC = 100°C) Pulsed drain current (3) Maximum power dissipation (4) ESD Rating Recommended Operation Conditions (5) Operating junction temp (TJ) .... -40°C to +125°C Thermal Resistance (6) θJA θJC Notes: 2) Exceeding these ratings may damage the device. 3) Repetitive rating: Pulse width = 100µs, duty cycle limited by maximum junction temperature. 4) TA = +25°C. The maximum allowable power dissipation is a function of the maximum junction temperature T J (MAX), the junction-to-ambient thermal resistance θ JA, and the ambient temperature TA. The maximum allowable continuou s power dissipation at any ambient temperature is calculated by P D (MAX) = (T J (MAX) - TA) / θJA. Exceeding the maximum allowable power dissipation produces an excessive die temperature, causing the regulator to go into thermal shutdown. Internal thermal s hutdown circuitry protects the device from permanent damage. 5) The device is not guaranteed to function outside of its operating conditions. 6) Measured on JESD51-7, 4-layer PCB.
