Dual Mobile-Friendly DDR / Dual-output PWM Controller
Features
• Highly flexible dual synchronous switching PWM controller includes modes for: – DDR mode with in-phase operation for reduced channel interference – 90˚ phase shifted two-stage DDR Mode for reduced input ripple – Dual Independent regulators 180° phase shifted • Complete DDR Memory power solution – VTT Tracks VDDQ/2 – VDDQ/2 Buffered Reference Output • Lossless current sensing on low-side
MOSFET or precision over-current using sense resistor • VCC Under-
voltage Lockout • Converters can operate from +5V or 3.
3V or Battery power input (5 to 24V) • Excellent dynamic response with V...
