My customer is trying to use TPS57060 DCDC converter with configure of 2MHz condition.
System requirement :
- Vin range ( 10V to 32V)
- Vout = 9V
- Fsw = 1.9MHz to 2MHz
Q.1) Inside the datasheet, only Ton-min typical value is described as 130ns. Could you provide upper limit of Ton-min to judge if it's available with 2MHz operation?
Q.2) If required on-time < Ton-min, is there any concern in terms of operation other than frequency shift down to AM frequency range?
Q.3) When Vin=10V, duty would be 90%. Will this condition be OK with TPS57060 as it's described device operates with 100% duty?
