- The high current path from the board’s input to the load (via
Q
1) and the return path should be parallel and close to each
other to minimize parasitic loop inductance.
- The ground connections for the various components around
the LM25066 should be connected directly to each other and
to the LM25066’s GND pin and then connected to the system
ground at one point. Do not connect the various component
grounds to each other through the high current ground line.
For more details, see application note AN-2100.
- Provide adequate heat sinking for the series pass device
(Q
1) to help reduce stresses during turn-on and turn-off.
- Keep the gate trace from the LM25066 to the pass MOSFET
short and direct.
- The board’s edge connector can be designed such that the
LM25066 detects via the UVLO/EN pin that the board is being
removed and responds by turning off the load before the sup-
ply voltage is disconnected. For example, in Figure 17, the
voltage at the UVLO/EN pin goes to ground before V
SYS is
removed from the LM25066 because of the shorter edge con-
nector pin. When the board is inserted into the edge connec-
tor, the system voltage is applied to the LM25066’s VIN pin
before the UVLO voltage is taken high, thereby allowing the
LM25066 to turn on the output in a controlled fashion.
