LTC1436AIGN - Dual Output Synchronous Step-Down Switching Regulator

The LTC1436AIGN, a product from Linear Technology, is a high-performance dual output synchronous step-down switching regulator designed for precision voltage regulation in a variety of applications. This integrated circuit (IC) is a feature-rich solution for systems requiring efficient power conversion with minimal external components.

Key Features:

• Wide Input Voltage Range: The LTC1436AIGN operates from an input voltage range of 4.5V to 36V, making it suitable for a variety of supply sources, from standard 5V rails to higher voltage batteries and industrial supplies.
• Dual Synchronous Outputs: This regulator provides two synchronous outputs, which are capable of delivering up to 1.5A each with high efficiency. The synchronous architecture reduces power losses and improves overall system efficiency.
• Adjustable Switching Frequency: The switching frequency is programmable from 150kHz to 300kHz, allowing designers to optimize the trade-off between efficiency and component size.
• Independent Soft-Start Functions: Each output has an independent soft-start function which gradually increases the output voltage to the regulated level, preventing inrush current and voltage overshoot at startup.
• Current Mode Operation: The current mode control provides excellent transient response and cycle-by-cycle current limiting for enhanced protection.
• Low Dropout Operation: The LTC1436AIGN can operate with a very low dropout voltage, which is ideal for applications where the input voltage is close to the output voltage.
• Thermal Protection: Built-in thermal protection shuts down the regulator in the event of excessive heat, safeguarding the IC and the system it powers.
