MAX17482GTL+集成電路（IC）的特殊用途穩(wěn)壓器規(guī)格書PDF中文資料

General Description

The MAX17021/MAX17082/MAX17482 are 2/1-phase interleaved Quick-PWM? step-down VID power-supply controllers for notebook CPUs. True out-of-phase operation reduces input ripple current requirements and output- voltage ripple, while easing component selection and layout difficulties. The Quick-PWM control provides instantaneous response to fast load-current steps. Active voltage positioning reduces power dissipation and bulk output capacitance requirements and allows ideal positioning compensation for tantalum, polymer, or ceramic bulk output capacitors.
