QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 623

550KHZ MICROPOWER STEP-DOWN DC/DC CONTROLLER

LTC3801

DESCRIPTION

Demonstration circuit 623 is a step-down (buck)

regulator, using the LTC

3801 monolithic controller.

The DC623 has an input voltage range of 2.5V to 9.8V

and is capable of providing 1A at an output voltage of

2.5V from a single Li-Ion cell. The DC623 highlights

the capabilities of the LTC3801, a constant frequency

step-down DC-to-DC controller that comes in a tiny

SOT-23 package and runs off extremely low quiescent

currents. The LTC3801 uses a current mode PWM

architecture to drive an external P-channel power

MOSFET in a buck regulator application. The result is

a high performance power supply that is ideal for cell

phones and other portable electronics operating from

one or two Li-ion cell. Due to the use of surface

mount components, the DC623 is a highly efficient

power supply for use in very small spaces.

Design files for this circuit board are available. Call the

QUICK START PROCEDURE

Demonstration circuit 623 is easy to set up to evalu-

ate the performance of the LTC3801. Refer to

Figure 1 for proper measurement equipment setup

and follow the procedure below:

NOTE:

When measuring the input or output voltage

Turn on the input power supply, set to 5V,

with no load on the output. Measure

OUT

; it should be 2.5V ±3% (2.425V to

2.575V).

Vary the load current from no load to 1A.

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 Figure 2 for proper scope probe technique.

The output voltage should be within a

tolerance of ±4% (2.4V and 2.6V).

Vary the input voltage from 2.7V to 9.8V.

The output voltage should be within ±5%

tolerance (2.375V and 2.625V).
