Other Parts Discussed in Thread: TPS62821, TLV62568
Hi,
I'm looking at the TPS62560 for a new design and am trying to establish the voltage output accuracy.
I noted that the Vfb is specified for PWM mode as +/- 2.5% over 2.5V to 5.5V and full current + temperature range, however, there is a footnote that suggests that this is "For Vin = Vout + 0.6V". The switcher claims to be capable of 100% duty cycle so I was planning on using this device to switch in some situations as low as Vin=3.6V to Vout=3.3V. Will the Vfb accuracy be affected if I operate with VIN less than "Vout + 0.6V"?
Thanks
Phil
