The LM53603-Q1, LM53602-Q1 buck regulators are specifically designed for automotive applications, providing an output voltage of 5 V or 3.3 V (with ADJ option) at 3 A or 2 A, from an input voltage of up to 36 V. Advanced high-speed circuitry allows the device to regulate from an input of up to 20 V, while providing an output of 5 V at a switching frequency of 2.1 MHz. The innovative architecture allows the device to regulate a 3.3 V output from an input voltage of only 3.5 V. All aspects of this product are optimized for the automotive customer. An 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 delay, 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 no-load operating current of only 24 µA, ensures high efficiency and superior transient response at all loads.
