Boost converter

Switching regulator that steps voltage up.

How it looks

Drawing: this is not on CORE3588, so it is drawn

A boost converter. CORE3588 has none: its 5 V input is already above every rail it needs.

How it works

HOW A BOOST STEPS VOLTAGE UPinput3.7 Voutput5 Vinductorswitch to groundone-way valveswitch to ground: current builds up in the coilswitch opens: the coil's push adds to the inputrepeat very fast: the capacitor holds the higher voltage

Where it fits

The mirror of a buck converter; both in one is a buck-boost. Several of them in one chip make a PMIC.
