Nameplate capacitance values (the effective values are lower based on the applied DC voltage and temperature).

As discussed in Power Supply Recommendations, an electrolytic bulk capacitance (68 µF to 100 µF) provides

low-frequency filtering and parallel damping to mitigate the effects of input parasitic inductance resonating with

the low-ESR, high-Q ceramic input capacitors.

8.3.4 Output Capacitors

Table 8-1 lists the TLVM13610 minimum amount of required output capacitance. The effects of DC bias and

temperature variation must be considered when using ceramic capacitance. For ceramic capacitors in particular,

the package size, voltage rating, and dielectric material contribute to differences between the standard rated

value and the actual effective value of the capacitance.

When including additional capacitance above COUT(min), the capacitance can be ceramic type, low-ESR polymer

type, or a combination of the two. See Table 8-3 for a preferred list of output capacitors by vendor.

8.3.5 Switching Frequency (RT)

Connect a resistor, designated as RRT in Figure 8-1, between RT and AGND to set the switching frequency

within the range of 200 kHz to 2.2 MHz. Refer to Equation 5 to calculate RRT for a desired frequency.

RRTkΩ =  16.4

FSW MHz −0.633

(5)

Refer to Table 8-1 or use the simplified expression in Equation 5 to find a switching frequency that sets an

inductor ripple current of 25% to 40% of the 8-A module current rating at nominal input voltage.

8.3.6 Precision Enable and Input Voltage UVLO (EN)

The EN pin provides precision ON and OFF control for the TLVM13610. After the EN pin voltage exceeds the

rising threshold and VIN is above its minimum turn-on threshold, the device starts operation. The simplest way to

enable the TLVM13610 is to connect EN directly to VIN. This action allows the TLVM13610 to start up when VIN
