Decoupling capacitors for V
decoupling of the TS4621ML. An X5R dielectric and 10 V rating voltage is
recommended to minimize ΔC/ΔV when V
Must be placed as close as possible to the TS4621ML to minimize parasitic
inductance and resistance.
Capacitor for internal negative power supply operation. An X5R dielectric
and 6.3 V rating voltage is recommended to minimize ΔC/ΔV when
HPVDD = 1.9 V.
Must be placed as close as possible to the TS4621ML to minimize parasitic

Filtering capacitor for internal negative power supply. An X5R dielectric and
6.3 V rating voltage is recommended to minimize ΔC/ΔV when
HPVDD = 1.9 V.
Input coupling capacitor that forms with R
filter with a -3 dB cut-off frequency Fc.
Output capacitor of 0.8 nF minimum to 100 nF maximum. This capacitor is
mandatory for operation of the TS4621ML.
Output resistor in-series with the TS4621ML output. This 12 Ω minimum
resistor is mandatory for operation of the TS4621ML.
Inductor for internal DC/DC step-down converter.
