Device description
5.1
Oscillator
The switching frequency can be fixed to two values: 250KHz or 500KHz by setting the proper
voltage at the EAREF pin (see Table 3. 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 VCC
The LDO can be by-passed, providing directly a 5V voltage to VCCDR. In this case VCC and
least 1F capacitor to sustain the internal LDO during the recharge of the bootstrap capacitor.
