LTC3634MPUFD#PBF

The LTC3634MPUFD#PBF created by Linear Technology is part of the company\'s PMIC - Voltage Regulators - Special Purpose lineup, designed to provide users with programmable general purpose supplies. The device provides a number of features, including programmable output voltage, synchronizable programmable switching frequency, programmable soft-start, programmable power-good, and input voltage regulation with elimination of the need for a discrete linear regulator.

The device is especially suitable for applications requiring a low noise, high efficiency and high current output. It is intended to be used in wired and wireless base station power supply units, e-book readers, and other battery-powered applications. The LTC3634MPUFD#PBF offers the same features as the LTC3625MPUFD#PBF, but also with reverse current blocking.

Typical Application

The LTC3634MPUFD#PBF is typically used in applications such as power supplies and powering electronic devices. It can be used to provide a regulated output voltage from a wide range of input voltages. This makes it an ideal choice for providing power in a high voltage environment, such as a battery powered application.

Working Principle

The LTC3634MPUFD#PBF operates by combining an input voltage regulation and an output voltage regulation into a single device. The input voltage regulation uses a power MOSFET to provide isolation from the input voltage, while the output voltage regulation uses a buck converter to generate a regulated output voltage. In addition, the device includes a synchronizable programmable switching frequency, which can be adjusted to minimize the device\'s output noise levels. The device also includes a programmable soft-start, programmable power-good, and a reverse current blocking feature, which prevents undesirable reverse current into the input voltage.

Conclusion

The LTC3634MPUFD#PBF is a special purpose voltage regulator that provides users with programmable output voltage and programmable switching/output ranges, in addition to its other features. This device is ideal for powering electronic devices in applications where a high efficiency and low noise output voltage is necessary. It operates by combining an input voltage regulation and an output voltage regulation into one device, making it an all-round great choice for many applications.
