Part Number: MAX17409

Function: 1-Phase Quick-PWM NVIDIA CPU Controller

Package: 28 TQFN Type

Manufacturer: Maxim Integrated

Pinouts:

 

Description

The MAX17409 is a 1-phase Quick-PWM™ step-down VID power-supply controller for high-performance graphics processors. The Quick-PWM control provides instan taneous 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.

Features

1. 1-Phase Quick-PWM Controller

2. ±6mV VOUTAccuracy Over Line, Load, and Temperature

3. 6-Bit Graphics DAC (12.5mV LSB)

4. Active Voltage Positioning with Adjustable Gain

5. Accurate Droop and Current Limit

6. Remote Output and Ground Sense

7. Buffered 2V Reference Output for Offsets

8. Power-Good Window Comparator

9. Temperature Comparator

10. Drives Large Synchronous Rectifier FETs

11. Adjustable Switching Frequency (600kHz max)

12. Output Overvoltage and Undervoltage Protection

13. Soft-Startup and Soft-Shutdown
