LT3493IDCB#PBF - Linear Technology

The LT3493IDCB#PBF is a cutting-edge, micropower step-up DC/DC converter with an integrated Schottky diode and output disconnect, designed and manufactured by Linear Technology. This high-performance component is crafted to deliver a compact and efficient solution for portable and battery-powered applications where space and power consumption are critical considerations.

Operating from an input voltage range of 2.5V to 16V, the LT3493IDCB#PBF is versatile enough to accommodate a variety of power sources, including single-cell lithium-ion batteries. It can generate an adjustable output voltage up to 34V, which makes it ideal for OLED and LCD bias supply applications. Its internal 350mA switch can deliver output voltages as high as 34V from an input voltage as low as 2.5V.

One of the key features of this product is its ability to disconnect the output from the input during shutdown. This feature ensures minimal leakage current (

The device also includes a unique control scheme that allows for constant-frequency switching, making it possible to maintain a consistent noise profile across the entire range of input voltages and output loads. This is particularly beneficial for noise-sensitive applications.

For protection, the LT3493IDCB#PBF integrates several features including current limiting and thermal shutdown. These protective measures ensure reliable operation under a wide range of conditions, safeguarding both the converter and the end application from potential damage.

The package for the LT3493IDCB#PBF is a 6-lead DFN, which is known for its small footprint and excellent thermal performance. This product is suitable for a wide array of applications, including OLED displays, organic polymer light-emitting diodes (P-OLED), charge pumps for flash photography, and small LCD bias supplies.
