QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 1158A

MONOLITHIC SYNCHRONOUS BUCK REGULATOR

LTC3564

DESCRIPTION

Demonstration circuit DC1158A is a high efficiency

monolithic synchronous buck regulator using a

constant frequency, current mode architecture fea-

turing LTC3564. Its high switching frequency of

2.25MHz allows the use of small surface mount

inductors and capacitors. Supply current during

operation is only 20uA dropping to below 1uA in

shutdown. The 2.5V to 5.5V input voltage range

makes the LTC3564 ideally suited for single Li-Ion

battery-powered or 3.3V to 5V input voltage appli-

cations. 100% duty cycle provides low dropout

operation, extending battery life in portable sys-

tems. Automatic Burst Mode® operation increases

efficiency at light loads, further extending battery

runtime.

able. Call the LTC Factory.

QUICK START PROCEDURE

The DC1158A is easy to set up to evaluate the

performance of the LTC3564. For a proper

measurement equipment configuration, set up

the circuit according to the diagram in Figure 2.

NOTE: When measuring the input or output volt-

age ripple, care must be taken to avoid a long

ground lead on the oscilloscope probe. Measure

the input or output voltage ripple by touching the

probe tip directly across the V

or V

OUT

and GND

terminals. See the Measurement Equipment Set-

up diagram in Figure 1 for proper scope probe

technique.

Please follow the procedure outlined below for

proper operation.

1. Connect the input power supply to the V

and GND terminals. Connect the load between

the V

OUT

and GND terminals. Refer to Figure 2

for the proper measurement equipment setup.

2. Before proceeding to operation, insert

jumper shunt XJP1 into the OFF position and

insert jumper shunt into XJP2, XJP3 or XJP4

for voltages of 1.2V, 1.5V or 1.8V respectively.

Set the load output current to less than 1.25A.

An optional output voltage can be set by popu-

lating resistor RFB6, removing RFB5 and mov-

ing the shunt jumper to JP5.

3. Apply 5V at V

. Measure V

OUT

; it should

read 0V. If desired, one can measure the shut-

down supply current at this point. The supply cur-

rent will be about 1 µA in shutdown.

4. Turn on V

OUT

by changing shunt XJP1 from

the OFF position to the ON position. The out-

put voltage should measure according to the
