32 / 160 page  Page 32 ams Datasheet, Confidential Document Feedback [v1-00] 2014-Sep-10 AS3715 − Detailed Description – Power Management Functions Figure 33: Low Power LDO External Components Low Power LDO External Components: Shows the external component parameter of the low power V2_5 linear regulator. DCDC Step-up Converter Description The DC/DC Step Up converter is a high efficiency current mode PWM regulator, which provides an output voltage dependent on the maximum VDS voltage of the external transistor, and maximum load current selectable by the external shunt resistor. For Example: • 5V, 0.5-1A @ 1Mhz • 25V, 50mA @ 1MHz • 40V, 20mA @ 500kHz A constant switching frequency results in a low noise on supply and output voltage. Three feedback regulation modes are supported: • Current feedback (all three current sinks can be selected) • Current feedback with automatic feedback selection •Voltage feedback Symbol Parameter Conditions Min Typ Max Unit CV2_5 Output capacitor Ceramic X5R or X7R 0.7 μF |
