The LTC1628IG#TRPBF is a high performance dual step-down switching regulator controller from LT, designed to drive all N-channel synchronous power MOSFET stages. It features a constant frequency current mode architecture, allowing for frequency adjustment up to 300kHz. The controller operates with a wide input voltage range of 3.5V to 36V, making it suitable for various battery-powered applications.
Key electrical specifications include a 99% duty cycle for very low dropout operation and an output voltage accuracy of –1%. The device supports adjustable soft-start current ramping and foldback output current limiting. It also includes latched short-circuit shutdown with a defeat option and output overvoltage protection.
Available in a 28-pin SSOP package, the LTC1628IG#TRPBF is designed for surface mount applications. Its out-of-phase controller operation minimizes input capacitance requirements and power supply induced noise. OPTI-LOOP compensation is utilized to optimize transient response over a range of output capacitance and ESR values.
The input voltage range is 3.5V to 36V.
The operating frequency can be programmed from 150kHz to 300kHz.
The output voltage accuracy is –1%.
It features a 99% duty cycle for very low dropout operation.
The shutdown current is 20mA.
The operating temperature range is -40°C to 85°C.
It is available in a 28-pin SSOP package.
