Beschreibung
PMP15019 uses the LM5141-Q1 low Iq synchronous buck controller as the centerpiece of a high current automotive DC/DC power supply. The PMP15019 operates over the input voltage range of VOUT + 0.5V to 42V. The EVM provides a 5.0V output (default) with a maximum load current of 15A, 20A transient. The device offers configurability and VOUT can be set to 3.3V and the oscillator frequency can be set up to switch at 440 kHz (default) or 2.2 MHz.
