Working Principles

The LTC3626EUDC#TRPBF operates as a step-down (buck) converter, converting a higher input voltage to a lower output voltage. It utilizes a switching regulator topology to efficiently regulate the output voltage. The feedback voltage (FB) pin is used to set the desired output voltage, while the enable pin (EN) controls the device's on/off state.

When enabled, the IC switches the input voltage through an internal switch (SW) at a high frequency. This switching action, along with the inductor and capacitor connected in the circuit, creates a regulated output voltage. The power good indicator (PG) pin provides a signal indicating that the output voltage is within the specified range.

Detailed Application Field Plans

The LTC3626EUDC#TRPBF is suitable for various applications, including but not limited to: - Battery-powered devices - Portable electronics - IoT (Internet of Things) devices - Wearable devices - Industrial equipment - Automotive electronics
