PMIC - Voltage Regulators - DC DC Switching Controllers

The ZL6105ALBFTKR5554 is a DC to DC controller designed for use in power supply applications such as battery-powered portable electronic devices. It is a highly integrated IC specifically designed to provide high performance, low cost, and low power consumption.

Application areas

The ZL6105ALBFTKR5554 DC to DC controller is suitable for both step-up (boost) and step-down (buck) voltage conversion applications. It is ideal for use in various power supply applications, such as battery-powered portable electronic devices, automotive or avionics systems, communication systems, building automation and other distributed power systems.

Working principle

The ZL6105ALBFTKR5554 DC to DC controller operates in a pulse-width modulation (PWM) mode. It starts a cycle by turning on an external power switch at the beginning of a cycle and then turning off the switch at a preset peak current limit threshold. The controller then records the current feedback voltage and monitors it throughout the cycle. Based on the monitored current feedback voltage and the preset parameters set in the controller, the duration of each on and off period is adjusted accordingly. This process is repeated in each cycle until the predetermined target output voltage is reached.
