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
