Follow these general guidelines when
designing the power supply:
- The power supply must be designed to provide the
operating conditions outlined in the recommended
operating conditions section in terms of DC voltage,
AC noise, and start-up ramp time.
- The TDP2004 does not require
any special power supply filtering, such as ferrite
beads, provided that the recommended operating
conditions are met. Only standard supply decoupling
is required. Typical supply decoupling consists of a
0.1µF capacitor per VCC pin, one 1.0µF bulk
capacitor per device, and one 10µF bulk capacitor
per power bus that delivers power to one or more TDP2004 devices. The local
decoupling (0.1µF) capacitors must be connected as
close to the VCC pins as possible and with minimal
path to the TDP2004 ground
pad.
