FDMF5821DC – Smart Power Stage (SPS) Module

with Integrated Temperature Monitor

Features

Description

Ultra-Compact 5 mm x 5 mm PQFN Copper-Clip

Package with Flip Chip Low-Side MOSFET and

Dual Cool Architecture

The SPS family is Fairchild’s next-generation, fully

optimized, ultra-compact, integrated MOSFET plus

driver power stage solution for high-current, high-

frequency, synchronous buck, DC-DC applications. The

FDMF5821DC integrates a driver IC with a bootstrap

Schottky diode, two power MOSFETs, and a thermal

monitor into a thermally enhanced, ultra-compact, 5 mm

x 5 mm package.

High Current Handling: 60 A

3-State 5 V PWM Input Gate Driver

Dynamic Resistance Mode for Low-Side Drive

(LDRV) Slows Low-Side MOSFET during Negative

Inductor Current Switching

With an integrated approach, the SPS switching power

stage is optimized for driver and MOSFET dynamic

performance, minimized system inductance, and power

MOSFET R_DS(ON). The SPS family uses Fairchild's high-

performance PowerTrench^®MOSFET technology,

which reduces switch ringing, eliminating the need for a

snubber circuit in most buck converter applications.

Auto DCM (Low-Side Gate Turn Off) Using

ZCD# Input

Thermal Monitor for Module Temperature Reporting

Programmable Thermal Shutdown (P_THDN)

HS-Short Detect Fault# / Shutdown

A driver IC with reduced dead times and propagation

delays further enhances the performance. A thermal

monitor function warns of a potential over-temperature

situation. A programmable thermal shutdown function

turns off the driver if an over-temperature condition

occurs. The FDMF5821DC incorporates an Auto-DCM

Mode (ZCD#) for improved light-load efficiency. The

FDMF5821DC also provides a 3-state 5 V PWM input

for compatibility with a wide range of PWM controllers.

Dual Mode Enable / Fault# Pin

Internal Pull-Up and Pull-Down for ZCD# and

EN Inputs, respectively

Fairchild PowerTrench^®MOSFETs for Clean

Voltage Waveforms and Reduced Ringing

Fairchild SyncFET™ Technology (Integrated

Schottky Diode) in Low-Side MOSFET

Integrated Bootstrap Schottky Diode

Applications

Optimized / Extremely Short Dead-Times

Under-Voltage Lockout (UVLO) on VCC

Optimized for Switching Frequencies up to 1.5 MHz

PWM Minimum Controllable On-Time: 30 ns

Low Shutdown Current: < 3 µA

Servers and Workstations, V-Core and Non-V-Core

DC-DC Converters

Desktop and All-in-One Computers, V-Core and

Non-V-Core DC-DC Converters

High-Performance Gaming Motherboards

Optimized FET Pair for Highest Efficiency:

10 ~ 15% Duty Cycle

High-Current DC-DC Point-of-Load Converters

Operating Ambient Temperature Range:

-40°C to +125°C
