Description
The SRK2000 smart driver implements a control scheme specific to secondary-
side synchronous rectification in LLC resonant converters that use a
transformer with center-tap secondary winding for full-wave rectification.
It provides two high-current gate-drive outputs, each capable of driving one
or more N-channel Power MOSFETs. Each gate driver is controlled separately and
an interlocking logic circuit prevents the two synchronous rectifier MOSFETs
from conducting simultaneously.
Features
■ Secondary-side synchronous rectifier controller optimized for LLC resonant
converters
■ Protection against current reversal
■ Safe management of load transient, light load and startup condition
■ Intelligent automatic sleep-mode at light load
■ Dual gate driver for N-channel MOSFETs with 1 A source and 3.5 A sink drive
current
■ Operating voltage range 4.5 to 32 V
■ Programmable UVLO with hysteresis
■ 250 µA quiescent consumption
■ Operating frequency up to 500 kHz
■ SO8 package
Applications
■ All-in-one PC
■ High-power AC-DC adapters
■ 80+/85+ compliant ATX SMPS
■ 90+/92+ compliant server SMPS
■ Industrial SMPS
