Description
The LT3470ETS8#TRPBF is a high-efficiency step-up DC/DC converter designed by Analog Devices under the Linear Technology brand. It is packaged in a compact TSOT-23-8 form, making it suitable for space-constrained applications. This converter offers a wide input voltage range, typically from 2.4V to 16V, and can deliver output voltages up to 40V. The device is known for its high efficiency, often exceeding 80%, due to its use of a 1.2MHz fixed switching frequency, which reduces inductor and capacitor sizes.
This converter integrates a power switch, oscillator, over-current protection, and current mode control for fast transient response and stability. It also features a soft-start function to prevent inrush current during startup and a low shutdown current to save power when the device is not in use. The LT3470ETS8#TRPBF is typically used in applications such as OLED power supplies, TFT-LCD bias supplies, and other portable electronics requiring efficient voltage boosting. Its compact size and high efficiency make it ideal for modern, battery-powered devices.
