The LTC3862HUH#PBF features a 32-lead QFN package with the following pin configuration:
The LTC3862HUH#PBF is a high-efficiency synchronous buck controller designed to regulate the output voltage from an input voltage source. It utilizes a pulse-width modulation (PWM) control scheme to adjust the duty cycle of the switching transistor, thereby regulating the output voltage.
The controller operates by comparing the feedback voltage (FB) with a reference voltage to generate an error signal. This error signal is then processed by the internal control circuitry to adjust the duty cycle of the switching transistor. By continuously monitoring and adjusting the duty cycle, the controller maintains a stable output voltage despite variations in the input voltage or load conditions.
The LTC3862HUH#PBF is suitable for a wide range of applications, including:
These alternative models offer similar functionality and performance to the LTC3862HUH#PBF but may differ in package type or operating temperature range.
