Hi,
I’m looking for a pin-pin compatible replacement for Diode Inc AP61100.
A replacement that can perform 100% duty cycle in order to produce 3V (or 2.8V) from battery (until 3.2V)
Seems MP1601 and MP2141 can (duty cycle claimed to be 100%), but datasheet have very few information on that.
Do you confirm that both these parts can?
When using design tool Off Time Limit is reached
Is that off time required for bootstrap recharge?
I do not see the point of being 100% duty cycle if off time is required (sory for my lack of knbowledge on DCDC…)
Also, why MP1601 and MP1601A are so difficult to buy? There is no availability at all…
BR
Would there be an MPS guy to help me please?
Hello,
Yes, both of the MP1601 / MP2141N are capable of 100% dutycycle. One of the main advantages is lower RDson for MP2141N.
Regarding off-time, I believe you referring to min-off time. This is accounted for in high dutycycle operation.
Regards,
Nouman
