Hi Team,

Customer's circuit demand is Vin=40~60V, Vout=40~60V, Iout=10A_max. Do we have any suitable buck controller solution to recommend? The duty cycle is required to be 100%. Thanks.

Best,

Stanley

Hello Stanley

Unfortunately, LM5088's duty cycle cannot be 100% since the device requires forced 280ns off-time.

LM5085 (https://www.ti.com/product/LM5085)can achieve 100% duty cycle .
