Power supply modules
In total 11 power supply modules are available in the PCF50603; see Table 1:
Three regulators for supplying the digital and analog circuitry (D1REG, D2REG and D3REG). These regulators support
the ECO mode
One regulator for high current supply (HCREG)
One regulator for the SIMI supply (SIMREG)
One charge pump (CP)
One regulator for supplying the I/O pads (IOREG). This regulator supports the ECO mode
One regulator for low power supply (LPREG). This regulator supports the ECO mode, the LPREG is the only regulator
that can be enabled in SAVE and STANDBY state (ECO mode only)
Two low-noise regulators for RF supply (RF1REG and RF2REG)
One ultra low-noise regulator for supplying a microphone (MBGEN).
Table 1
Power supply modules; VSS = REFGND = GND = 0 V; Tamb = 40 °C to +85 °C; unless otherwise specied.
Notes
1. Typical value, 100 Hz < f < 1000 Hz.
2. Typical values assume X5R or X7R type of capacitor.
3. Mask programmable for reset settings of different types.
4. Under specific conditions a nominal current of 300 mA can be delivered.
5. When SIMI is in Power-down mode.
6. Maximum current depends on the selected output voltage. At 3.50 V, 4.00 V and 4.50 V the maximum output current
is 75 mA. At 5.00 V output voltage the maximum output current is 50 mA.
7. The CP module requires both a switching capacitor as well as an output capacitor.
8. Optimized for low noise (30
V RMS value, 400 Hz < f < 80 kHz).
