Device description
Oscillator
The switching frequency can be fixed to two values: 250KHz or 500KHz by setting the proper
voltage at the EAREF pin (see
reference).
Internal LDO
An internal LDO supplies the internal circuitry of the device. The input of this stage is the V
pin and the output (5V) is the V
The LDO can be by-passed, providing directly a 5V voltage to V
