PMIC – Voltage Regulators – DC DC Switching Regulators

The LTC3528BEDDB#TRMPBF chip is a step-up DC-DC converter specifically designed to power high current devices such as LEDs, LCDs and processors. It is a type of DC-DC switching regulator, so it is an example of a voltage regulator that works by rapidly switching current on and off in the input source to create an output voltage.

The LTC3528BEDDB#TRMPBF is incredibly versatile in its applications. With features like step-up, step-down, buck-boost, and inverting output, it is easily adapted to any voltage regulation requirements. It can drive up to 4A output currents over an input voltage range of 2.3V to 20V, making it possible to use for a wide range of devices, from low current LCDs to high powered processors. The device also features thermal protection and current limit, making it safe to operate in the event of thermal overload or mechanical breakage.

Working Principle

The LTC3528BEDDB#TRMPBF works by rapidly switching current on and off in the input source to create an output voltage. The device uses a technique known as Pulse Width Modulation (PWM) in order to convert the input voltage into a regulated output voltage. The device works by switching off the switch in the linear regulator when the required output voltage is reached. This switch allows the current flow to be regulated and the output voltage to remain relatively constant. The switching frequency of the LTC3528BEDDB#TRMPBF can be adjusted using the included on-chip oscillator.

The on-chip oscillator and PWM control circuit is programmed to achieve the desired output voltage. This programming is done by adjusting the frequency of the on-chip oscillator, which is typically fixed at 1MHz. The PWM duty cycle is adjusted to provide the desired output voltage and current. Additionally, the LTC3528BEDDB#TRMPBF features an adaptive output voltage control that can be used to dynamically adjust the output voltage in response to changes in input voltage or load conditions.

The LTC3528BEDDB#TRMPBF is equipped with short circuit protection, thermal shutdown and over-voltage protection. The device also includes an integrated power MOSFET switch and a current-limit level adjust pin which can be used to set the maximum output current.
