产品说明

The LM53600/01 synchronous buck regulator is optimized for automotive applications, providing either an adjustable output or an output voltage of 3.3 V or 5 V. The LM53600-Q1 device supports load currents up to 650 mA and the LM536001-Q1 supports load currents up to 1000 mA.

Advanced high speed circuitry allows the device to regulate from an 18-V input to a 3.3-V output at a fixed frequency of 2.1 MHz. Innovative architecture allows the device to regulate a 3.3-V output from an input voltage of only 3.8 V. Input voltage range up to 36 V, with transient tolerance up to 42 V, eases input surge protection design.

An open drain reset output, with filtering and delayed release, provides a true indication of system status. This feature negates the requirement for an additional supervisory component, saving cost and board space. Seamless transition between PWM and PFM modes, along with a quiescent current of only 22 µA, ensures high efficiency and superior transient response at all loads. Few external components are needed allowing the generation of compact PCB layout. The device characteristics are specified from a junction temperature range of –40°C up to 150°C.
