MAX1981A規(guī)格書詳情
General Description
The MAX1907A/MAX1981A are single-phase, Quick-PWM? master controllers for IMVP-IV? CPU core supplies. Multi-phase operation is achieved using a Quick-PWM slave controller (MAX1980). Multiphase operation reduces input ripple current requirements and output voltage ripple while easing component selection and layout difficulties.
Features
? Quick-PWM Master Controllers
? Multiphase Conversion with Slave Controller
?? (MAX1980)
? Active Voltage Positioning with Adjustable Gain
