APU3146
Advanced Power Electronics Corp. recently introduced
a new pulse width modulated (PWM) dual synchronous
buck controller APU3146. This is a driver
IC for point-of-load (POL) buck converters.
Typical applications include dual phase ASIC
and DDR memory power management circuits,
datacom, telecommunications, PC Power related
power supplies requiring multiple outputs.
APU3146 is an ideal PWM IC for two-phase single-
or dual-output synchronous buck converter applications.
In single output two-phase applications, the
solution can deliver up to 30A. In applications
where two separate voltages are required, the
solution will deliver up to 15A per output.
The product features for APU3146 include
．Dual Synchronous Controller with 180O out-of-phase
．Current Sharing Using Inductor's DCR
．Current Limit using MOSFET's RDS(ON)
．Hiccup/Latched Current Limit
．Latched Over-Voltage Protection
．Programmable Switching Frequency up to 500KHz
．Two Independent Soft-Starts/ Shutdowns
．0.8V Precision Reference Voltage Available
．Power Good Output
．External Frequency Synchronization
AP30G120W
APEC fast series of Insulated Gate Bipolar
Transistors (IGBTs) provide low conduction
& switching losses. AP30G120W is designed
for applications such as Induction Heater & Micro
Oven where high speed switching is a required
feature.
