TPS40090EVM-001
概覽
The TPS40090EVM−001 multi-phase dc-to-dc converter utilizes the TPS40090 multi-phase controller and UCC27222 predictive gate driver to step down a 12-V input to 1.5-V at 420 kHz. The output current is 100 A. The TPS40090 provides fixed-frequency, peak current-mode control with forced-phase current balancing. Phase currents are sensed by the voltage drop across the DC resistance (DCR) of inductors. Other features include a single voltage operation, true differential output voltage sense, user programmable current limit, capacitor-programmable soft-start and a power good indicator. Device operation is specified in the TPS40090 datasheet.
