IRDCiP1201-A is a kind of 300kHz, Dual 15A, 3.14VIN to 5.5VIN dual output synchronous buck converter using iP1201.It is fully optimized solution for medium current synchronous buck applications requiring up to 15 A or 30 A.
What comes next is about the demoboard quick start guide.First is about the initial settings.The output1 is set to 1.5 V and output2 is set to 2.5 V for independent configuration.The output1 is set to 1.5V with R8, R10, R11 and R12 removed for parallel configuration.Output can fbe adjusted rom 0.8 V to 3.3 V as follow:1.VOUT1: R9=R13= R7 [(VOUT 1/ Vref) 1]. Set R7=R14=1k,Vref=0.8V;2.VOUT2: R10=R11= R8 [(VOUT2 / Vref) 1]. Set R8=R12=1k,Vref=0.8V.The switching frequency is set to R3=30.9k for 300kHZ.The input voltage range can be increased to allow operation between 3.14VIN and 5.5VIN.Then is procedure for connecting and powering up demoboard:1.Connected JP2 for VIN < 3.5V;2.Disconnected JP2 for VIN > 3.5V;3.Make sure JP3 is connected;4.Apply input voltage (3.14 V-5.5 V) across VIN and PGND;5.Apply load across VOUT1 pad and PGND pad and VOUT2 pad and PGND pad for independent configuration;6.Apply load across VOUT1 pad and PGND pad and short R23 for parallel configuration;7.Adjust load accordingly.
The following is about the recommended operating conditions (refer to the iP1201 datasheet for maximum operating conditions).The input voltage is from 3.14 to 5.5 V.The output voltage can be set between 0.8V and 3.3V, up to 90% max duty cycle.The output current is up to 15 A.The maximum current should be limited to 11.5 A if the PCB is the only heat sink.The switching frequency is from 200kHz to 400kHz selectable.
