Device description
5.1
Oscillator
The switching frequency can be fixed to two values: 250 kHz or 500 kHz by setting the
proper voltage at the EAREF pin (see Table 4. Pins function and section 4.3 Internal and
external reference).
5.2
Internal LDO
An internal LDO supplies the internal circuitry of the device. The input of this stage is the
The LDO can be by-passed, providing directly a 5 V voltage to VCCDR. In this case VCC and
at least 1 F capacitor to sustain the internal LDO during the recharge of the bootstrap
