500kHz Multi-Output, Low-Noise Power-Supply
Controllers for Notebook Computers
Note 1: Each of the four digital soft-start levels is tested for functionality; the steps are typically in 20mV increments.
Note 2: High duty-factor operation supports low input-to-output differential voltages, and is achieved at a lowered operating frequency
Note 3: MAX1902 only.
Note 4: Off mode for the 12V linear regulator occurs when the SMPS that has flyback feedback (V
Note 5: Since the reference uses V
Note 6: Production testing limitations due to package handing require relaxed maximum on-resistance specifications for the thin
Note 7: Specifications from to 0°C to -40°C are guaranteed by design, not production tested.
