Infineon 36-Pin, PG-DSO-36 PWM Controller, 425 kHz, 45V, PCB

The Infineon next generation microcontroller supply e is a multifunctional power supply circuit especially designed for Automotive powertrain systems using a standard 12 V battery. The device is intended to supply and monitor next generation 32-bit microcontroller families where voltage levels such as 5 V, 3.3 V or 1.5/1.2/1.3 V are required. The regulator follows the concept of its predecessor microcontroller, where the output of a pre-regulator feeds the inputs of the micros linear supplies. In detail, the microcontroller cascades a Buck converter with linear regulators and voltage followers to achieve lowest power dissipation. This configuration allows to power the application even at high ambient temperatures.
