VRM10 Series
Single output
NEW Product
Filename: vrm10_u_p.pdf Rev (01): 26 Aug 2004
Designed for use in low profile applications where VRM10.0 or
10.1 specifications are required
Output current up to 85A continuous
Open-collector power good (PWRGD) output
6-bit microprocessor voltage identification input (VID)
- 0.8375V to 1.6000V in 12.5mV steps
- Allows dynamic VID code changes
Differential remote sense for improved load regulation
Vertical plug-in to standard motherboard connector
Selectable output load line impedances, via LL0 and LL1
Output over-voltage signal (OVP)
Monotonic output turn-on and turn-off with no overshoot or
undershoot
The VRM10 non-isolated DC/DC converter is designed to meet the exceptionally fast
transient response requirements of today’s microprocessors and fast switching logic in a
compact size at a very affordable price. Advanced Circuit techniques, component selection
and placement optimization, state-of-the-art thermal packaging, and surface-mount
Technologies provide a high power density, highly reliable, and very precise voltage
regulation system for advanced microprocessors.
2 YEAR WARRANTY
Unless otherwise stated, all specifications are typical at nominal input, maximum
continuous rated load at 25°C and voltages are referenced to Vin-.
