Series
MAX17019r
Datasheet
19-5936; Rev 0; 6/11
The MAX17019N evaluation kit (EV kit) demonstrates
the MAX17019’s standard application circuit. This quad-
output converter steps down high-voltage batteries and/
or AC adapters, generating main supplies for ultra-
mobile PCs (UMPCs).
The EV kit provides a 5V main stage output voltage
(VOUTA), a 1.8V VDDQ output voltage (VOUTB), a 1.05V
chipset supply output voltage (VOUTC), and a 0.9V VTT
output voltage (VOUTD) from a 6V to 38V battery input
range. It delivers up to 4A output current for the 5V out-
put, 2.5A for the 1.8V output, 4A for the 1.05V output, and
2A for the 0.9V output. The 1.8V VDDQ and 0.9V VTT are
for DDR2 memory applications. All outputs are adjust-
able by changing feedback resistors R5–R10.
The IC also has an internal fixed 5V linear regulator
capable of supplying 50mA. The EV kit operates at
0.5MHz (VOUTA and VOUTC) and at 1MHz switching
frequency (VOUTB). The EV kit has superior line- and
load-transient response.
This EV kit is a fully assembled and tested circuit board.
It also allows the evaluation of other fixed output voltages
by changing R5–R10 resistors.
