3.1 Introduction
LPC55Sxx series requires single 1.8 to 3.6 V operation voltage supply.
LPC55S0x/LPC550x, LPC55S1x/LPC551x, LPC55S2x/LPC552x and LPC55S6x/LPC556x internal core’s voltage are supplied
by internal DC/DC regulator, this DC/DC regulator needs external inductance and two or three capacitors. For details, see
Using
the DCDC feature
(document AN12325).
