Wide input range dual PWM controller with DDR option. Suitable for single and dual channel DDR memory power systems, graphics cards - GPU and memory supplies, supplies for servers, motherboards, FPGAs, ASIC power supplies, embedded processor and I/O supplies, DSP supplies applications.

• Provides regulated output voltage in the range of 0.9V to 5.5V
• Complete DDR memory power solution with VTT tracks VDDQ/2 and VDDQ/2 buffered reference output
• Supports both DDR-I and DDR2 memory
• Lossless rDS(ON) current-sense sensing
• Excellent dynamic response with voltage feed-forward and current mode control
• Dual mode operation - operates directly from a 5.0V to 15V input or 3.3V/5V system rail
• Undervoltage lock-out on VCC pin
• Power-good, overcurrent, overvoltage, undervoltage protection for both channels
• Synchronized 300KHz PWM operation in PWM mode
