PRELIMINARY VICBrick V•I Chip VICBrick DC-DC Converters Quarter Brick, 48 Vin Family Features 1.0 to 5.0 Vdc Output TM • Up to 80 A continuous, 100 A surge • 93% efficiency @ 5 Vdc • 100°C operating case temperature • 180 W/in3 power density 120 A/in3 • 36 – 75 Vdc input range • 100 V input surge for 100 ms • Low noise ZCS/ZVS architecture • Fast dynamic response • Parallelable, with fault tolerance • 2,250 Vdc basic insulation Product Overview VICBrick high-density converters (up to 120 A/in3) are enabled by Vicor’s V•I Chip technology. Each VICBrick consists of two V•I Chips: a 36 – 75 Vdc input Pre-Regulator Module (PRM) that is paired with an appropriate Voltage Transformation Module (VTM) chosen to provide the desired output voltage. While the ultra-low profile package conforms to industry-standard quarter-brick footprint (1.45" x 2.28"), it stands only 0.27" high and achieves 80 A of output current. Standard outputs include 1.0, 1.2, 1.5 V and 1.8 V at 80 A, 2.5 V at 60 A, 3.0 and 3.3 V at 45 A, and 5 V at 30 A. Output voltages can be easily trimmed up or down over a wide range. Dual output pins are used for output currents over 50 A. Utilizing breakthrough Sine Amplitude Converter (SAC) technology, VICBricks offer the highest efficiency, lowest noise, fastest transient response and highest power density. And because of the V•I Chips highly integrated functionality, VICBricks have only a fraction of the parts of a typical DC-DC converter.

The VICBrick’s internal under/over voltage lockout-function prevents operation outside of the normal input range. The VICBrick turns ON within an input voltage window bounded by the "Input under-voltage turn-on" and "Input overvoltage turn-off" levels, as specified. The module may be protected against accidental application of a reverse input voltage by the addition of a rectifier in series with the positive input, or a reverse rectifier in shunt with the positive input located on the load side of the input fuse. +OUT / – OUT — DC Voltage Output Pins The 0.060" diameter + and – output pins are rated for a maximum current of 50 A. Two sets of pins are provided for all units with a current rating over 50 A. These pins must be connected in parallel with minimal interconnect resistance. Input impedance Vicor recommends a minimum of 10 µF bypass capacitance be used on-board across the +IN and –IN pins. The type of capacitor used should have a low Q with some inherent ESR such as an electrolytic capacitor. If ceramic capacitance is required for space or MTBF purposes, it should be damped with approximately 0.3 Ω series resistance. +SENSE / –SENSE — Remote Sense Pins Remote sense minimizes the effects of distributiion losses by regulating the voltage at the remote sense connections. Output impedance The very low output impedance of the VICBrick reduces or eliminates the need for limited life aluminum electrolytic or tantalum capacitors at the input of the non-isolated point-of-load converters. The DC resistance of the source should be kept as low as possible. ON/OFF PIN The ON/OFF pin provides the following Enable/Disable functionality: Standard "M" configuration — If the ON/OFF pin is left floating, the module output is disabled. Once this port is pulled lower than 0.7 Vdc with respect to –IN, the output is enabled. This action can be realized by employing a relay, opto-coupler or open collector transistor. This pin should not be toggled at a rate higher than 1 Hz. Optional "P" configuration — This is the reverse function from above: when the ON/OFF pin is left floating, the module output is enabled. Once this port is pulled lower than 1.7 Vdc with respect to –IN, the output is disabled. If not using the ON/OFF pin function, perform one of the following to turn the converter on: For M configuration, short ON/OFF pin to –IN. For P configuration, leave ON/OFF pin open.
