TPS2410 EVM (HPA204)

2

MOSFET Configurations

The TPS2410 EVM is supplied with IRL3713 MOSFETS. These MOSFETs can be replaced with user
selected parts if desired as there are alternative MOSFET footprints that accept N-channel parts in
D2PACK, DPACK, and SOIC packages. The schematic is shown in

Section 4

.

The MOSFETs are configured to operate as singles with only Q6 and Q13 populated as supplied. They
may be configured to operate in parallel on the PS1 channel by populating Q6 and Q5 and shorting drain
to source on Q4. Similarly, for parallel operation on the PS2 channel, populate Q13 and Q12 and short
drain to source on Q11. MOSFETs can be configured back-to-back by populating only Q4 and Q5 on
channel 1, and Q12 and Q11 on channel 2.

In single or parallel configurations, the body diode of the MOSFET limits V

AC

to 0.7 V. For back to back

MOSFETs, there could be a danger of exceeding the V

AC

operating maximum 5 V. The V

AC

protect circuit

is a low powered FET that is turned on when V

AC

approaches the maximum.

3

LED Indicators

Each channel has LED indicators for fault (FLTB), gate status (STAT), and power good (PG).

Table 1

summarizes the indicators. Each indicator is labeled on the circuit board for easy reference.
