产品介绍
IR3504MPBF
| Features |
- 2 converter outputs for the AMD processor VDD core and VDDNB auxiliary planes
- AMD Serial VID interface independently programs both output voltages and operation
- Both Converter Outputs boot to 2-bit ?Boot? VID codes which are read and stored from the SVC & SVD parallel inputs upon the assertion of the Enable input
- PWROK input signal activates SVID after successful boot start-up
- Both Converter Outputs can be independently turned on and off through SVID commands
- Deassertion of PWROK prior to Enable causes the converter output to transition to the stored Pre-PWROK VID codes
- Connecting the PWROK input to VCCL disables SVID and implements VFIX mode with both output voltages programmed via SVC & SVD parallel inputs per the 2 bit VFIX VID codes
- PG monitors output voltage, PG will deassert if either ouput voltage out of spec
- 0.5% overall system set point accuracy
- Programmable Dynamic VID Slew Rates
- Programmable VID Offset (VDD output only)
- Programmable output impedance (VDD output only)
- High speed error amplifiers with wide bandwidth of 20MHz and fast slew rate of 10V/us
- Remote sense amplifiers provide differential sensing and require less than 50uA bias current
- Programmable per phase switching frequency of 250kHz to 1.5MHz
- Daisy-chain digital phase timing provides accurate phase interleaving without external components
- Hiccup over current protection with delay during normal operation
- Central over voltage detection and communication to phase ICs through IIN (ISHARE) pin
- OVP disabled during dynamic VID down to prevent false triggering
- Detection and protection of open remote sense lines
- Gate Drive and IC bias linear regulator control with programmable output voltage and UVLO
- Simplified Power Good (PG) Output provides indication of proper operation and avoids false triggering
- Small thermally enhanced 32L MLPQ (5mm x 5mm) package
- Over voltage signal to system with over voltage detection during powerup and normal operation
