TPS650362-Q1中文资料适用于摄像头模块且具有三个降压转换器和一个 LDO 稳压器、高达 ASIL B 等级的汽车级 35V PMIC数据手册TI规格书

描述 Description

The TPS65036x-Q1 device is a highly integrated power management IC for automotive camera and radar modules and MCU power. This device combines three step-down converters and one low-dropout (LDO) regulator. The BUCK1 step-down converter has an input voltage range up to 35 V. All converters can operate in a forced fixed-frequency PWM mode or an AutoPFM mode and support optional Spread-Spectrum Modulation (SSM) for EMI reduction. The LDO can supply 300 mA and operate with an input voltage range from 3 V to 5.5 V. The TPS65036x-Q1 support Low Power Mode with control from pin or I2C.

The TPS65036x-Q1 is available in a 24-pin VQFN package (3.5 mm × 3.5 mm).
