ISL6445规格书详情
1.4MHz Dual, 180° Out-of-Phase, Step-Down PWM Controller
The ISL6445 is a high-performance, dual-output PWM controller optimized for converting wall adapter, battery or network intermediate bus DC input supplies into the system supply voltages required for a wide variety of applications. Each output is adjustable down to 0.8V. The two PWMs are synchronized 180o out-of-phase reducing the RMS input current and ripple voltage.
Features
• Wide Input Supply Voltage Range
- 5.6V to 24V
- 4.5V to 5.6V
• Two Independently Programmable Output Voltages
• Switching Frequency . . . . . . . . . . . . . . . . . . . . . . .1.4MHz
• Out-of-Phase PWM Controller Operation
- Reduces Required Input Capacitance and Power Supply Induced Loads
• No External Current Sense Resistor
- Uses Lower MOSFET’s rDS(ON)
• Programmable Soft-Start
• Extensive Circuit Protection Functions
- PGOOD
- UVLO
- Overcurrent
- Over-temperature
- Independent Shutdown for Both PWMs
• Excellent Dynamic Response
- Voltage Feed-Forward with Current Mode Control
• Pb-Free (RoHS Compliant)
Applications
• Power Supplies with Two Outputs
• xDSL Modems/Routers
• DSP, ASIC, and FPGA Power Supplies
• Set-Top Boxes
• Dual Output Supplies for DSP, Memory, Logic, µP Core and I/O
• Telecom Systems
