Description

This design uses a synchronous buck converter to provide light load efficiency with predictable ripple off "Telecom" voltage range. This approach is described in the TPS54061 datasheet from page 23 onwards. A low fixed frequency of 50kHz with operation in the discontinuous mode at all, but the highest loading achieves excellent efficiency at light loads without the "burst mode" which creates unpredicable ripple. PMP9535 extends operation into the 36-57V input range, and demonstates stability at 150mA load where conduction becomes continuous.
