TP8472BPXC Datasheet Notes 1. CPD iS used to determine the dynamic power dissipation (PD in W) PD = CPD x VCC2 x fi + . (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; * (CL x VCC2 x fo) = sum of outputs; CL = output load capacitance in pF; Vcc = supply voltage in Volts. 2. The condition is VI = GND to Vcc. TP8472BPXC Price

A floating power supply for the switcher is generated by D2 and C3 which peak detect the input voltage during switch off time.Thisis differentthanthe 5Vve rsion ofthe LT1432 which connects the anode of the diode to the output ratherthan the input. The output connection is more efficient because the floating voltage is a constant 5V (or 3.3V), independent of input voltage, but in the case of the 3.3V circuit, minimum required input voltage for starting is several volts higher (see the Typical Performance Characteristics curves). When the diode is connected to the input, the suggested type is a |
