The LTC1628IG#TRPBF from Analog Devices is a high-performance, dual step-down switching regulator controller designed to drive N-channel synchronous power MOSFET stages. It features a constant frequency current mode architecture with an adjustable frequency up to 300kHz, and the datasheet specifies a typical operating frequency of 220kHz.
This controller offers a wide input voltage range of 3.5V to 30V and supports very low dropout operation with a maximum duty cycle of 99.4%. Key control features include Enable, Frequency Control, Power Good, and Soft Start, allowing for adjustable soft-start current ramping. The device is available in a 16-SSOP package, suitable for surface mount applications.
Designed for high efficiency, the LTC1628IG#TRPBF utilizes out-of-phase controllers to minimize input capacitance and power supply induced noise. OPTI-LOOP compensation is employed to optimize transient response over a wide range of output capacitance and ESR values. The device also includes foldback output current limiting and latched short-circuit shutdown with a defeat option.
