Ericsson POL regulators are implemented by using non-isolated synchronous buck topology shown in Figure 1. During normal operation of a buck power stage, QH and QL are alternatively switched on and ...
Hardware-design engineers have long recognized the usefulness of RC lowpass filters (Figure 1). Lowpass filters are useful for performing signal conditioning, removing noise from a signal, or ...
To reduce noise levels, the LTC3201 charge-pump, white LED driver integrates an input noise filter and uses a constant frequency switching topology to minimize input current noise. This results in an ...
