ISL6225CAZ规格书详情
The ISL6225 dual PWM controller delivers high efficiency and tight regulation from two voltage regulating synchronous buck DC/DC converters. The ISL6225 PWM power supply controller was designed especially for DDR DRAM, SDRAM, and graphic chipset applications in high performance desknote PCs, notebook PCs, sub-notebook PCs, and PDAs.
Automatic mode selection of constant-frequency synchronous rectification at heavy load, and hysteretic diode-emulation at light load, assure high efficiency over a wide range of conditions. The hysteretic mode of operation can be disabled separately on each PWM converter if constant-frequency continuous-conduction operation is desired for all load levels. Efficiency is further enhanced by using the lower MOSFET rDS(ON) as the current sense element.
Features
• Provides regulated output voltage in the range of 0.9V-5.5V
- High efficiency over wide load range
- Synchronous buck converter with hysteretic operation at light load
- Inhibit Hysteretic mode on one, or both channels
• Complete DDR memory power solution
- VTT tracks VDDQ/2
- VDDQ/2 buffered reference output
• No current-sense resistor required
- Uses MOSFET rDS(ON)
- Optional current-sense resistor for precision overcurrent
• Under-voltage lock-out on VCC pin
• Dual input voltage mode operation
- Operates directly from battery 5V to 24V input
- Operates from 3.3V or 5V system rail
- VCC from 5V only
• Excellent dynamic response
- Combined voltage feed-forward and average current mode control
• Power-good signal for each channel
• 300kHz switching frequency
- 180° channel to channel phase operation for reduced input ripple when not in DDR mode
- 0° channel to channel phase operation in DDR mode for reduced channel interference
- 90° channel to channel phase operation for reduced input ripple in DDR mode when VIN is at GND.
• Pb-Free Available (RoHS Compliant)
Applications
• Mobile PCs
• PDAs
• Hand-held portable instruments
