As an example, waveforms for 60 V version, EPC9049 operation as a 48 V to 5 V/ 4 A (1000kHz) buck
converter
CH1: VPWM Input voltage – CH2: (IOUT) Switch node current – CH4:
(VOUT) Switch node voltage
* Assumes inductive load, maximum current
depends on die temperature – actual maximum current will be subject to switching frequency, bus voltage and
thermal cooling.
# Dependent on time needed to ‘refresh’ high side bootstrap supply voltage.
