DEMO CIRCUIT 1672A

QUICK START GUIDE

LTC3816EUHF

HIGH EFFICIENCY SINGLE PHASE BUCK CONVERTER

FOR INTEL IMVP-6/IMVP-6.5 CPUs

DESCRIPTION

Demonstration circuit 1672A is a high efficiency,

single phase, synchronous buck converter for Intel

IMVP-6/IMVP-6.5 CPUs. It can supply 25A maxi-

mum load current at up to 1.5V output with 4.5V to

28V input range. The demo board features the

LTC®3816EUHF controller. The LTC3816 is a sin-

gle-phase synchronous buck controller in a con-

stant-frequency voltage mode architecture. The con-

troller’s leading edge modulation topology allows

extremely low output voltages and supports a phase-

lockable switching frequency up to 550kHz. The

output voltage is programmed using a 7-bit VID

code. The default VID jumpers (VID6 to VID0) are

set to be 0110000 for 0.9V output. The LTC3816

features all of the IMVP-6/IMVP-6.5 requirements,

including start-up to a preset boot voltage, differen-

tial remote output voltage sensing with programma-

ble active voltage positioning, Imon output current

reporting, power optimization during sleep state, and

slow slew rate sleep state exit. Fault protection fea-

tures include input undervoltage lockout, cycle-by-

cycle current limit, output overvoltage protection,

and power-good (PWRGD) and overtemperature

flags. The LTC3816 supports wide input range (4.5V

to 36V) with optional line feedforward compensation,

temperature compensated inductor DCR or sense

resistor output current monitoring. The LTC3816

can provide high efficiency, high power density and

PARAMETER

Performance Summary (T

CONDITION

versatile power solutions for embedded computing,

mobile computers, internet devices and navigation

displays. The controller is available in 38-pin ther-

mally enhanced eTSSOP and 5mm × 7mm QFN

packages.

The VRON pin (JP15) provides enable feature. To

shut down the converter, one simple way is to force

the VRON pin below 0.65V (JP15: OFF). Use JP19

jumper to select pulse-skipping or forced continuous

mode operation. Switching frequency is pre-set at

about 400KHz, and it can be easily modified from

150KHz to 550KHz. JP20~JP26 (VID0~VID7) are

used to set the output voltage based on the IMVP-

6/IMVP-6.5 VID code, as shown in table 2. JP1 and

JP18 are used to select either IMVP6 or IMVP6.5

specification. For detailed information, please see

LTC3816 data sheet and Intel IMVP-6/IMVP-6.5 spe-

cification.

Design files for this circuit board are available. Call

the LTC factory.
