LTC3252EDE#TRPBF - A High-Efficiency, Dual-Output Step-Down Charge Pump

The LTC3252EDE#TRPBF is a versatile and robust dual-output step-down charge pump designed by Linear Technology, a leader in the design and manufacture of high-performance analog integrated circuits. This component is engineered to efficiently convert a higher voltage input to two lower voltage outputs, making it an ideal choice for portable devices where power efficiency and space are critical considerations.

The LTC3252EDE#TRPBF operates over a wide input voltage range of 2.7V to 5.5V, which makes it compatible with a variety of power sources, from single-cell lithium-ion batteries to multi-cell alkaline/NiMH configurations or even USB power. Its dual outputs can be independently set to fixed voltages of 1.2V, 1.5V, 1.8V, 2.5V, or 3.3V, or can be adjusted to any value between 1.2V and VIN with external resistors, providing design flexibility for different application requirements.

The device features a low-noise charge pump architecture that maintains a constant switching frequency at all loads, minimizing noise and potential interference with other circuitry. Moreover, the LTC3252EDE#TRPBF offers high efficiency, which can be up to 96%, ensuring minimal power loss during the voltage conversion process and extending battery life in portable applications.

In terms of safety and reliability, the LTC3252EDE#TRPBF includes over-temperature and short-circuit protection. The thermal protection prevents damage to the device under extreme operating conditions, while the short-circuit protection ensures stability and safety in the event of an output short.

The LTC3252EDE#TRPBF is available in a compact, thermally efficient 14-lead DFN package with a low profile of only 0.75mm. This small footprint allows for its use in space-constrained applications such as handheld devices, wearables, and IoT sensors.

Overall, the LTC3252EDE#TRPBF from Linear Technology is a highly reliable and efficient solution for designers looking to implement a dual-output voltage supply in their electronic projects, with the assurance of high performance and quality that comes with the Linear Technology brand.
