Working Principle

The LMS3635NQRNLTQ1 is a DC/DC switching regulator. It performs a buck-boost and a boost-buck conversion in such a way as to ensure a maximum efficiency. The switching regulator consists of four main stages: an integrated control circuit, a pulse width modulator (PWM), a voltage regulator, and an external MOSFET.

When the load current is drawn from the output, the voltage drop across the output terminal decreases the voltage feedback, which is provided to the control circuit. The regulator then adjusts the duty cycle in order to maintain the desired set point. The duty cycle is adjusted to achieve the desired voltage by increasing or decreasing the on-time of the MOSFET. The voltage regulator then controls the voltage on the output side to achieve the desired output voltage.

The integrated control circuit contains all the necessary functions for current and voltage control. It includes a variable frequency oscillator and a PWM circuit, which controls the current and the voltage feedback, respectively. The device also features embedded protection features such as over temperature protection and under voltage lockout, which prevents the device from entering an unsafe operating condition.

The LMS3635NQRNLTQ1 is a very efficient DC/DC switching regulator, as it provides consistent voltage and current regulation with a minimum of external components. It is highly reliable, as it features various protection features and has a high switching frequency, which reduces component size, cost, and losses.
