Example Application Circuit
Requirements:
Vin:
12V
Vout: 1.8V
Iout: 9A max., worst case load transient is from 6A to 9A
ΔVout: 1.5% of Vout (27mV) for worst case load transient
Vin, ripple 1.5% of Vin (180mV, p-p)
CI1 Decoupling cap - 1x0.047 μF/16V ceramic capacitor (e.g. Murata LLL185R71C473MA01)
CI2 2x22 μF/16V ceramic capacitor (e.g. Murata GRM32ER61C226KE20)
CI3 470 μF/16V bulk electrolytic
CO1 Decoupling cap - 1x0.047 μF/16V ceramic capacitor (e.g. Murata LLL185R71C473MA01)
CO2 2 x 47 μF/6.3V ceramic capacitor (e.g. Murata GRM31CR60J476ME19)
CO3 1 x 330 μF/6.3V Polymer (e.g. Sanyo Poscap)
CTune 3300pF ceramic capacitor (can be 1206, 0805 or 0603 size)
RTune 270 ohms SMT resistor (can be 1206, 0805 or 0603 size)
RTrim 10k Ω 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.
