The LMS36355QRNLRQ1 is one of the most powerful and versatile DC DC switching regulator ICs available, designed to provide voltage regulation in a wide range of applications. The device integrates both a single-stage PWM buck regulator and a two-stage buck-boost regulator with two independent current-mode regulated outputs. The LMS36355QRNLRQ1 is capable of operating from a wide input voltage range, from 0.8V to 15V, and is suitable for a wide range of power management applications.

The LMS36355QRNLRQ1 is designed for regulating multiple outputs with adjustable output voltage, including applications with complex power regulation schemes. It can be used to provide an adjustable single output of 0.6V to 5.5V, and a dual output ranging from 0.6V to 5.5V. The device features current mode control, real-time power-saving, over-temperature and over-voltage protection, and can operate in burst and pulse-skipping modes with low quiescent current. It also includes an integrated low dropout (LDO) regulator, a delay off circuit providing protection against inrush current, and an analog transient suppression circuit which can protect the outputs against short-term over-voltage conditions.

The main source of regulation, or controlling factor, for the LMS36355QRNLRQ1 is an internal PWM controller, which will regulate the output voltage at a frequency set by an external resistor. The device utilizes a so-called "duty cycle-based control" and has an internal monitoring protocol that provides an adequate level of system security. This PWM controller is incorporated into a buck-boost converter configuration, which allows for greater efficiency when operating from an input source with a wide range of voltage levels. The device offers an integrated protection against transient over-voltages and short-term over-voltage and over-current conditions.

The working principle of the LMS36355QRNLRQ1 is based on the switching action of a pair of MOSFETs, Q1 and Q2, and the primary components of the circuit are the inductor L1, the switching MOSFETs, and their associated circuit components. The switching MOSFETs operate in their linear regions and control the current through the inductor to the output. The current through the inductor is controlled by the low side MOSFET Q1, and the voltage is controlled by the gate driver relying on a PWM signal. In the circuit, a voltage is converted from one value to another, either a higher or lower voltage than the source. This voltage conversion is regulated by a feedback to the PWM circuit.

The LMS36355QRNLRQ1 is suitable for applications requiring a wide input voltage range, adjustable voltage outputs, and over-voltage and over-temperature protection. A few examples of the device’s applications include MCUs, DSPs, ASICs, I/Os, reference power supplies, automotive electronics, and telecommunications.
