Example Application Circuit
Requirements:
Vin: 12V
Vout: 1.8V
Iout: 2.25A max., worst case load transient is from 1.5A to 2.25A
ΔVout: 1.5% of Vout (27mV) for worst case load transient
Vin, ripple 1.5% of Vin (180mV, p-p)
CI1 Decoupling cap - 1x0.047μF/16V ceramic capacitor (e.g. Murata LLL185R71C473MA01)
CI2 1x22μF/16V ceramic capacitor (e.g. Murata GRM32ER61C226KE20)
CI3 470μF/16V bulk electrolytic
CO1 Decoupling cap - 1x0.047μF/16V ceramic capacitor (e.g. Murata LLL185R71C473MA01)
CO2 -
CO3 1x330uF
CTune 2200pF ceramic capacitor (can be 1206, 0805 or 0603 size)
RTune 220 ohms SMT resistor (can be 1206, 0805 or 0603 size)
RTrim 10kΩ SMT resistor (can be 1206, 0805 or 0603 size, recommended tolerance of 0.1%)
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.
