Part Number: TPS54240-Q1 Other Parts Discussed in Thread: TPS54240 We had some problems using TPS54240, so please look at the input: 12? 36V output requires 5V? 2A, actual measurement, Low efficiency (tested at input voltage 12V) 1A efficiency 78% 0.5A…
Part Number: TPS54240-Q1 Hello team,
At datasheet of TPS54240-Q1 is mentioned(32 page), An input voltage ripple is 206mV under Ioutmax = 2.5A, Cin = 4.4uF, Fsw = 300KHz.
Vin ripple = (Ioutmax x0.25) / Cin x Fsw (Equation 39)
But i can't get a answer of…
