Page 2: Introduction
Background The TPS54160EVM-230 provides two independent DC/DC converters based on the TPS54160. The converter at the top of the board (top converter) is designed to operate from a nominal 42VDC ±25% input voltage source. This input voltage range is typical for input supplies derived from rectified 24VAC sources. -
Page 3: Performance Specifications
VIN = 31.5V to 52.5V. Operation at other input voltages is possible but some performance specifications will vary compared to those shown in Table 2. The ambient temperature is 25°C for all measurements, unless otherwise noted. SLVU270 – September 2008 TPS54160EVM-230 Submit Documentation Feedback... -

Page 5: Synchronization To An External Clock
The UVLO and Enable levels are programmed using R8 and R9 on the EVM. See the TPS54160 data sheet for how to select the value of these resistors. Capacitor C19 can be installed to add a delay or noise filtering on the EN pin. SLVU270 – September 2008 TPS54160EVM-230 Submit Documentation Feedback... -
