QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 728

1MHZ SYNCHRONOUS STEP-UP DC/DC CONVERTER

LTC3458EDE

DESCRIPTION

Demonstration circuit 728 is a 1MHz Synchronous Step-

Up DC/DC Converter featuring the LTC®3458EDE. The

demo circuit demonstrates a DC/DC boost converter,

with a 1.5A switch, providing 7V at 200mA to 800mA

depending on input voltage. The circuit demonstrates

the advantages of output disconnect and inrush current

limiting. Small circuit size and low component count

make the LTC3458 suitable for use in many space-

conscious applications such as handheld instruments,

point-of-load converters, USB

BUS

Power and OLED

displays. Other integrated features include externally

programmable burst mode threshold, peak current limit,

soft-start, anti-ringing control and thermal shutdown.

NOTE: If supply is going to be used in

Fixed Frequency

Mode,

use a 50K Ohm resistor to tie the Burst pin to the

output voltage.

Design files for this circuit board are available. Call

the LTC factory.

LTC is a registered trademark of Linear Technology Corporation

C9 used only when operating supply with long inductive input leads.

QUICK START PROCEDURE

Demonstration circuit 728 is easy to set up to evaluate

the performance of the LTC3458EDE. Refer to Figure 1

for proper measurement equipment setup and follow the

procedure below:

measuring the input or output voltage rip-

ple, care must be taken to avoid a long ground lead on

the oscilloscope probe. Measure the input or output

NOTE:

When

voltage ripple by touching the probe tip directly across

the Vin or Vout and GND terminals. See Figure 2 for

proper scope probe technique.

Place jumpers in the following positions:

JP1 On, JP2 Auto On.
