provides much more output current and higher conversion efficiency. For these reasons, a 10-μH to 22-μH
inductor value range is recommended. A 22-μH inductor optimized the efficiency for most application while
maintaining low inductor peak-to-peak ripple. Table 4 lists the recommended inductor for the TPS61160 or
TPS61161. When recommending inductor value, the factory has considered –40% and 20% tolerance from its
nominal value.
The TPS61160 and TPS61161 have built-in slope compensation to avoid sub-harmonic oscillation associated
with current mode control. If the inductor value is lower than 10 μH, the slope compensation may not be
adequate, and the loop can be unstable. Therefore, customers need to verify the inductor in their application if it
is different from the recommended values.

8.2.1.2.3
Schottky Diode Selection
The high switching frequency of the TPS61160, TPS61161 demands a high-speed rectification for optimum
efficiency. Ensure that the diode average and peak current rating exceeds the average output current and peak
inductor current. In addition, the diode’s reverse breakdown voltage must exceed the open LED protection
voltage. The ONSemi MBR0540 and the ZETEX ZHCS400 are recommended for TPS61160 and TPS61161.
8.2.1.2.4
Compensation Capacitor Selection
The compensation capacitor C3 (see the Functional Block Diagram), connected from COMP pin to GND, is used
to stabilize the feedback loop of the TPS61160, TPS61161. A 220-nF ceramic capacitor for C3 is suitable for
most applications.
8.2.1.2.5
Input and Output Capacitor Selection
The output capacitor is mainly selected to meet the requirements for the output ripple and loop stability. This
ripple voltage is related to the capacitor’s capacitance and its equivalent series resistance (ESR). Assuming a
capacitor with zero ESR, the minimum capacitance needed for a given ripple can be calculated by:
where
Vripple = peak-to-peak output ripple
(6)
The additional output ripple component caused by ESR is calculated using:
(7)
Due to its low ESR, Vripple_ESR can be neglected for ceramic capacitors, but must be considered if tantalum or
electrolytic capacitors are used.
Care must be taken when evaluating a ceramic capacitor’s derating under DC bias, aging and AC signal. For
example, larger form factor capacitors (in 1206 size) have a resonant frequencies in the range of the switching
frequency. So the effective capacitance is significantly lower. The DC bias can also significantly reduce
capacitance. Ceramic capacitors can loss as much as 50% of its capacitance at its rated voltage. Therefore,
leave the margin on the voltage rating to ensure adequate capacitance at the required output voltage.
The capacitor in the range of 1 μF to 4.7 μF is recommended for input side. The output requires a capacitor in
the range of 0.47 μF to 10 μF. The output capacitor affects the loop stability of the boost regulator. If the output
capacitor is below the range, the boost regulator can potentially become unstable. For example, when using an
output capacitor of 0.1 μF, a 470-nF compensation capacitor has to be used for the loop stable.
