SUMMARIZED DESIGN PROCEDURE
Layout Considerations
SLVS728B – JANUARY 2007 – REVISED SEPTEMBER 2008.......................................................................................................................................... www.ti.com
The following is a summarized design procedure:
1. Choose between the TPS2412 or 2413, see TPS2412 vs TPS2413 – MOSFET Control Methods
2. Choose the VDD source. Table 3 provides a guide for where to connect VDD that covers most cases. VDD may
be directly connected to the supply, but an R(VDD) and C(VDD) of 10 and 0.01 F is recommended.
Table 3. VDD Connection Guide
VA < 3 V
3 V
≤ VA ≤ 3.6 V
VA > 3.6 V
Bias Supply > 3 V
VA or Bias Supply > 3 V. VC if always > 3 V
VC, VA, or Bias for special configurations
3. Noise voltage and impedance at the A pin should be kept low. C(A) may be required if there is noise on the
bus, or A is not low impedance. If either of these is a concern, a C(A) of 0.01 F or more may be required.
4. Select C(BYP) as 2200 pF, X7R, 25-V or 50-V ceramic capacitor.
5. Select the MOSFET based on considerations of voltage drop, power dissipated, voltage ratings, and gate
capacitance. See sections: MOSFET Selection and RSET and TPS2412 Regulation-Loop Stability.
6. Select R(RSET) based on which MOSFET was chosen and reverse current considerations – see MOSFET
Selection and RSET. If the noise and transient environment is not well known, make provision for R(RSET)
even when using the TPS2412.
7. Make sure to connect RSVD to ground
1. The TPS2412/13, MOSFET, and associated components should be used over a ground plane.
2. The GND connection should be short, with multiple vias to ground.
3. C(VDD) should be adjacent to the VDD pin with a minimal ground connection length to the plane.
4. The GATE connection should be short and wide (e.g., 0.025" minimum).
5. The C pin should be Kelvin connected to the MOSFET.
6. The A pin should be a short, wide, Kelvin connection to the MOSFET.
7. R(SET) should be kept immediately adjacent to the TPS2412/13 with short leads.
8. C(BYP) should be kept immediately adjacent to the TPS2412/13 with short leads.
