LTC3246IMSE#PBF is a monolithic synchronous DC-DC buck converter with a wide 2.7V to 5.5V input voltage range and an adjustable output voltage from 0.8V to 3.5V, making it ideal for point-of-load regulation in high current applications, such as point-of-load regulation in battery powered, handheld electronic devices. Different from other buck regulators, the LTC3246IMSE#PBF features an integrated PMOS and NMOS power switch, enabling the device to operate in switching and linear modes without external transistor. This feature also allows for low output ripple current and low quiescent current in both switching and linear operation modes.

The LTC3246IMSE#PBF’s ability to provide high current and low output ripple makes it ideal for a number of applications. It can be used in a variety of high-current portable systems, including power tools, cell phones, audio players, and even wearable devices.

The LTC3246IMSE#PBF consists of two key sections. The PWM (Pulse-width Modulation) control block adjusts the internal switching frequency and duty cycle to achieve the desired output voltage. The synchronous driver circuitry drives the external power MOSFETs to generate the output voltage. The device is capable of operating at switching frequencies from 100 kHz to 500 kHz, which allows for a diverse array of application solutions.

The integrated PMOS and NMOS switches are controlled by the integrated synchronous driver circuitry. The PWM control block converts the reference voltage and the feedback voltage into a PWM waveform. When the feedback voltage is lower than the reference voltage, the duty cycle of the PWM waveform increases accordingly and the output voltage increases. Conversely, when the feedback voltage is higher than the reference voltage, the duty cycle decreases and the output voltage decreases.

The output voltage of the LTC3246IMSE#PBF can be controlled via the internal reference voltage, external digital pulse width modulation (PWM) control, or a combination of both. In linear mode, the device can provide up to 5A output current with very low output ripple current. In switching mode, it can provide up to 20A output current with ultra-low output ripple current.

In summary, the LTC3246IMSE#PBF is a monolithic synchronous DC-DC buck converter that provides high accuracy and fast response features. It features an integrated PMOS and NMOS power switch, providing fast and efficient current transfer with low output ripple current. Its wide input voltage range, adjustable output voltage, and multiple modes of operation make it ideal for a wide range of high-current portable applications.
