The LTC3130IMSE#TRPBF is an integrated DC/DC buck-boost converter, designed to operate as a power management integrated circuit (PMIC). It combines a powerful buck converter capable of either step-up or step-down output voltage conversion and a low-dropout linear regulator (LDO) in a single integrated circuit. It is intended for use in battery-powered portable applications, as well as other applications with demanding supply chain requirements. The LTC3130IMSE#TRPBF provides an efficient, pre-configured buck-boost solution that is easy to integrate into systems, featuring automatic mode detection, wide input voltage range, low quiescent current, a wide output voltage range, and integrated voltage feedback clamps.

The LTC3130IMSE#TRPBF buck-boost converter uses a synchronous rectifier to provide an efficient conversion of the input voltage to any desirable regulated output voltage. The converter has an integrated switch with no Schottky diode, which maximizes efficiency performance and reduces external component count. The LTC3130IMSE#TRPBF also features two current-sensing functions, allowing it to monitor input current, output current, or both. The device also incorporates a low quiescent current LDO, ideal for portable electronic designs operating with battery power sources to ensure a steady output voltage.

The LTC3130IMSE#TRPBF can be programmed to provide a regulated output voltage or a fixed output ratio across the input voltage range, with a simple external resistor divider. Its input voltage range of up to 5.5V provides compatibility with USB, automotive battery, and other applications with varied supply voltages. The LTC3130IMSE#TRPBF is designed to be used with a minimum number of external components, eliminating the need for design optimization. It offers a wide output voltage range of up to 27V, allowing for maximum design flexibility.

The LTC3130IMSE#TRPBF includes a wide range of built-in features that make it a convenient and comprehensive power management solution. Its dual current sensing and current-limit feature allows the converter to limit current draw and optimize system performance. The LTC3130IMSE#TRPBF also features thermal shutdown protection, output voltage accuracy adjustment, phase-lockable frequency control, and over-voltage protection.

Moreover, the LTC3130IMSE#TRPBF features a shutdown pin that enables the system to enter a low-power state for power conservation. The device is protected against a wide range of circuit fault and input over-voltage conditions, and a built-in power-on reset function ensures consistent operation. In addition, the device includes an integrated voltage clamp circuit to protect the output voltage from reaching an unsafe level. This feature minimizes hardware complexity and allows the device to meet system safety requirements.

The LTC3130IMSE#TRPBF makes it easy to add power management capabilities to a system design. Its integrated synchronous buck-boost controller and low-dropout linear regulator provide a simple, efficient, and versatile solution for supplying regulated power. Its wide input voltage range and output voltage range, combined with its current-sensing capability and integrated fault protection, make it suitable for a variety of situations. The LTC3130IMSE#TRPBF is an ideal choice for applications requiring high efficiency and small footprint.
