57. EXAMPLE APPLICATION CIRCUIT

Requirements:

Vin:

12V

Vout:

1.8V

Iout:

4.5A max., worst case load transient is from 3A to 4.5A

Vout:

1.5% of Vout (27mV) for worst case load transient

Vin, ripple

1.5% of Vin (180mV, p-p)

CI1 Decoupling cap - 1x0.047

CI2 2x22

CI3 470

CO1 Decoupling cap - 1x0.047

capacitor

CO2 4x47

CO3 -

CTune 2200pF ceramic capacitor (can be 1206, 0805 or 0603 size)

RTune 300 ΩSMT resistor (can be 1206, 0805 or 0603 size)

RTrim 10k

Note: The DATA, CLK and SMBALRT pins do not have any pull-up resistors inside the module. Typically, the SMBus master controller will have

the pull-up resistors as well as provide the driving source for these signals.
