Rev 4.00
January 24, 2017 25A/35A DrMOS Module with Diode Emulation and PS4 Features The ISL99125B and ISL99135B are high-performance DrMOS
power modules designed for high-frequency power conversion.
By combining a high-performance FET driver and MOSFETs in
an advanced package, high-density DC/DC converters may be
created. Combined with an Intersil PWM controller, a complete
voltage regulator solution can be created with reduced
external components and minimum overall PCB real estate. VIN range: 0V to 25V Current capability: 25A (ISL99125B), 35A (ISL99135B) Supports three-state 5.0V PWM input 0.5О© ON-resistance and 4A sink current capability The ISL99125B and ISL99135B feature a three-state PWM
input that, working together with Intersil’s 5V PWM controllers
(such as ISL6398, ISL9585x, ISL637x, ISL633x, ISL636x, and
ISL68201), will provide a robust solution in the event of
abnormal operating conditions. Diode emulation for enhanced light-load efficiency The ISL99125B, ISL99135B support high-efficiency operations
not only at heavy loads, but also at light loads via its diode
emulation capability. Diode emulation can be disabled for
those applications where variable frequency operation is not
desired at light loads. Integrated high-side gate-to-source resistor to prevent self
turn-on due to high input bus dv/dt Ultra low shutdown supply current (3ВµA) for PS4 operation Low three-state hold-off time Adaptive shoot-through protection VCC undervoltage lockout Switching frequencies up to 2MHz Pb-free (RoHS compliant) ISL99125B, ISL99135B also feature very low shutdown supply
current (3ВµA) to ensure the low power consumption, especially
designed for IMVP8 PS4 shutdown operation. 3.5x5 QFN 24 Ld package Applications Related Literature High-efficiency and high-density VRM and VRD Core, graphic, and memory regulators for microprocessors For a full list of related documents, visit our website
