Supply voltage for the internal circuitry.
W hen set to logic level high, internal circuitry
of the device is enabled. W hen set to logic
level low, the PRD Y pin is forced low, the
Control and Sychronous switches are turned
off, and the supply current reduces to 10µ A.
T T L-level input signal to M OSFET drivers.
Power Ready - This pin indicates the status of
EN AB LE or V
low when EN ABLE is logic low or when V
is less than 4.4V (typ.). W hen EN AB LE is
logic high and V
this output is driven high. T his output has a
10mA source and 1mA sink capability.
Power G round - connection to the ground of
bulk and filter capacitors.
Switching N ode - connection to the output
inductor.

... To calculate power loss for a given set of operating conditions, the following procedure should be followed: Determine the maximum current for each iP2003A and obtain the maximum power loss from Fig 1. Use the curves in Figs and 6 to obtain normalized power loss values that match the operating conditions in the application. The maximum power loss under the operating conditions is then the product of the power loss from Fig ...

... One of the most critical elements of proper PCB layout with iP2003A is the placement of the external input bypass capacitors and the routing of the connecting power tracks recommended that the designer uses the following guidelines: 1. The diagram below suggests the addition of the input bypass capacitors either on the top side of the PCB (capacitors C1-C6) or top and bottom side (C7, C8), if placement on the bottom side is feasible ...
