APPLICATIONS INFORMATION
Layout Considerations
Due to the high impedances on the SD , V DD , and GATE
pins, these pins are susceptible to leakages to ground.
For example, a leakage to ground on SD will activate the
shutdown state if greater than 1.6μA. Providing adequate
spacing away from grounded traces and adding conformal
coating on exposed pins lowers the risk that leakage cur-
rent will interrupt system operation.
It is important to put the bypass capacitor, C1, as close as
possible to the OUT and V SS pins. Place the 10Ω resistor
as close as possible to the MOSFET gate pin. This will
limit the parasitic trace capacitance that leads to MOSFET
self-oscillation
The FB pin is sensitive to parasitic capacitance when the
regulation loop is closed. One result from this capacitive
loading is output oscillations during overvoltage regula-
tion. It is suggested that the resistors R FB1 and R FB2 be
placed close to the pin and that the FB trace itself be
minimized in size.
DESIGN EXAMPLE
Overview
The design process starts with minimum input voltage
start-up equations to calculate values for R SS and R IN .
These values need further refinement to meet two other
conditions: the maximum input voltage start-up condi-
tions and proper current for the charging of C1. The the
remaining element values are calculated based on the
input parameters.
Following are the input parameters for this example:
V SUPPLY(MIN) = 18V, V REG = 43V, V IN(MAX) = 250V, I LOAD =
1.5A at start-up, I LOAD = 3A after start-up, V TH = 5V
Important Electrical Characteristics table parameters used
in this example are summarized in Table 1.
Step 1: Maximum R SS
In this design example (Figure 6.) the component sizing
first considers the start-up phase after the charge pump
is active. The goal is to maximize the resistance of R SS
which still allows operation when the input voltage is at
the minimum value.
