Description
- 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
