The ASL2500SHNY is a highly integrated and flexible two-phase DC-to-DC boost converter IC developed by NXP Semiconductors. It is specifically designed for automotive LED lighting applications, providing an optimized supply voltage for multi-channel LED buck drivers.
This device features an SPI interface for control and diagnostic communication with an external microcontroller. It supports a wide input voltage range from 5.5 V to 40 V and can be configured via SPI for output voltages up to 80 V. The ASL2500SHNY operates with fixed frequency peak current mode control and includes features like parabolic/non-linear slope compensation. It can drive up to two external low-side N-channel MOSFETs and supports both logic and standard level MOSFETs.
The ASL2500SHN is housed in a 32-HVQFN package with an exposed thermal pad. It is AEC-Q100 Grade 1 qualified and operates within an ambient automotive temperature range of -40 °C to +125 °C. Additional features include input under-voltage lockout and thermal shutdown protection when the junction temperature exceeds +175 °C.
Key configurable parameters via SPI include supply under/over-voltage range, output voltage range, and DC-to-DC switching frequency, allowing for optimization of external components and EMC design. Diagnostic information, such as driver temperature, can also be accessed through the SPI interface.
