The TPS65037x-Q1 device is a highly integrated power management IC for automotive camera modules. This device combines three step-down converters and one low-dropout (LDO) regulator. The BUCK1 step-down converter operating input voltage range is up to 18V. The device can tolerate input voltage up to 36V (not recommended for a prolonged time period). All converters operate in a forced fixed-frequency PWM mode and support optional Spread-Spectrum Modulation (SSM) for EMI reduction. The LDO can supply 300mA and operate with an input voltage range from 2.5V to 5.5V. The TPS65037x-Q1 supports I2C control interface with interrupt pin or, alternatively, three GPIOs.

The TPS65037x-Q1 is available in a 18-pin WQFN-HR package (3mm × 2.5mm).
