APPLICATIONS INFORMATION
LEDs, D1 and D2, require around 3mA for good luminous
intensity. Accounting for a 2V diode drop and 0.5V VOL,
R1 and R2 are set to 2.7k.
PCB Layout Considerations
Connect the VIN and OUT pin traces as close as possible to
the MOSFET’s terminals. Keep the traces to the MOSFET
wide and short to minimize resistive losses. The PCB
traces associated with the power path through the MOSFET
should have low resistance. See Figure 8.
It is also important to put C1, the bypass capacitor for
the VCC pin, as close as possible between VCC and GND.
Also place C2 near the CPO and SOURCE pins. Surge
suppressors, when used, should be mounted close to the
LTC4352 using short lead lengths.
