Working Principle

The LTC3526LEDC-2#TRMPBF is a current-mode, synchronous step-down DC/DC converter. It utilizes an architecture that provides a high efficiency, low noise and low noise performance by combining the advantages of a synchronous design with current-mode control operations. It employs a fixed frequency, peak current mode PWM (Point-of-Load) controller. The accurate, low noise current mode operation of the controller allows excellent line and load transient response. The PWM works in a constant frequency, peak current mode with a duty cycle range of 0-100%. At heavy loads, the duty cycle will decrease to maintain a constant output voltage.

The LTC3526LEDC-2#TRMPBF is also equipped with an integrated high-side and low-side MOSFET drivers and a power stage built with an external N-channel MOSFET and P-channel MOSFET. The control signals from the PWM controller are connected to the MOSFET drivers in order to control the conduction of the MOSFETs. The MOSFET driver features a peak short current level of 100mA, allowing it to operate at very low RDS(on). The high efficiency is further improved with the use of the synchronous design, which results in lower power losses in the power stage and higher overall efficiency.

The LTC3526LEDC-2#TRMPBF also features a wide range of operating temperature range, allowing it to operate over a variety of temperature environments. The device also employs a number of protective features, such as over-temperature and undervoltage lockout, providing an extra layer of protection and providing reliable operation across a range of environmental conditions.
