QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 488
HIGH EFFICIENCY, LOW NOISE, INDUCTOR-LESS STEP DOWN DC/DC CONVERTER
LTC3250-1.5
DESCRIPTION
Demonstration circuit 488 is a high efficiency, inductor-
less step-down converter featuring the LTC3250-1.5.
The circuit produces a fixed 1.5V output from a 3.1V to
5.5V input.

the LTC factory.
QUICK START PROCEDURE
Demonstration circuit 488 is set up to easily evaluate the
performance of the LTC3250-1.5 low noise charge
pump. Refer to Figure 1 for proper measurement
equipment setup, and follow the procedure outlined be-
low:
When measuring the input or output voltage ripple, care
must be taken to avoid a long ground lead on the oscil-
loscope probe. Measure the input or output voltage rip-
ple by touching the probe tip directly across the Vin or
Vout and GND terminals. See Figure 2 for proper scope
probe technique.
1.
Connect jumper JP1 to the ON position.
2.
With power off, connect a 3.6V, 200mA power supply
to the Vin and GND terminals.
3.
Turn on the power at the input. Attach desired load
(up to 250mA) from Vout to GND
4.
Check for the proper output voltage. Vout = 1.44V to
1.56V.
