BD9F500QUZ-EVK-001 uses BD9F500QUZ to output 1V from a 12V input voltage.
The input voltage of the BD9F500QUZ is from 4.5V to 36V and the output voltage is configurable from 0.6V to 14V with external resistors. The operating frequency is selectable between 600 kHz, 1 MHz and 2.2 MHz. It is a fixed on-time controlled DC/DC converter that provides fast transient response. The light-load mode control improves efficiency at light loads which makes it ideal for devices that require less standby power. Built-in functions include variable soft start function which prevents inrush current at startup, UVLO (Under Voltage Lock Out), TSD (Thermal Shutdown Detection), OCP (Over Current Protection) and SCP (Short Circuit Protection).
