PI33xx-x0

Inductor Pairing

The PI33xx-x0 utilizes an external inductor. This inductor has been

optimized for maximum efficiency performance. Table 4 details

the specific inductor value and part number utilized for each

PI33xx-x0 device which are available from Coiltronics and Eaton.

Thermal Derating

Thermal de-rating curves are provided that are based on

component temperature changes versus load current, input

voltage and air flow. It is recommended to use these curves as a

guideline for proper thermal de-rating. These curves represent the

entire system and are inclusive to both the PI33xx-x0 regulator

and the external inductor. Maximum thermal operation is limited

by either the MOSFETs or inductor depending upon line and

load conditions.

Thermal measurements were made using a standard PI33xx-x0

Evaluation board which is 3 x 4 inches in area and uses 4-layer,

2oz copper. Thermal measurements were made on the three

main power devices, the two internal MOSFETs and the external

inductor, with air flows of 0, 200, and 400LFM.

Filter Considerations

The PI33xx-x0 requires input bulk storage capacitance as well as

low impedance ceramic X5R input capacitors to ensure proper

start up and high frequency decoupling for the power stage. The

PI33xx-x0 will draw nearly all of the high frequency current from

the low impedance ceramic capacitors when the main high side

MOSFET is conducting. During the time the high side MOSFET

is off, they are replenished from the bulk capacitor. If the input

impedance is high at the switching frequency of the converter,

the bulk capacitor must supply all of the average current into the

converter, including replenishing the ceramic capacitors. This value

has been chosen to be 100μF so that the PI33xx-x0 can start up

into a full resistive load and supply the output capacitive load with

the default minimum soft start capacitor when the input source

impedance is 50

Ω at 1MHz. The ESR for this capacitor should be

approximately 20m

Ω. The RMS ripple current in this capacitor is

small, so it should not be a concern if the input recommended

ceramic capacitors are used. Table 5 shows the recommended

input and output capacitors to be used for the various models

as well as expected transient response, RMS ripple currents per

capacitor, and input and output ripple voltages.

Table 6 includes the recommended input and output

ceramic capacitors.
