The LTC1628CG#TRPBF is a high-performance dual step-down switching regulator controller from Linear Technology. It drives all N-channel synchronous power MOSFET stages and features a constant frequency current mode architecture, allowing frequency adjustment up to 300kHz.
Key electrical specifications include a wide input voltage range of 3.5V to 36V and very low dropout operation with a 99% duty cycle. The output voltage accuracy is within -1%, and it supports adjustable soft-start current ramping. The device also includes foldback output current limiting and latched short-circuit shutdown.
Available in QFN and SSOP packages, the LTC1628CG#TRPBF is designed for applications such as notebook computers, battery chargers, and portable instruments. Its out-of-phase controllers minimize input capacitance and power supply induced noise, while OPTI-LOOP compensation optimizes transient response.
This controller offers selectable constant frequency or Burst Mode operation. It also features output overvoltage protection and remote output voltage sensing. The low shutdown quiescent current is 20mA.
The input voltage range is 3.5V to 36V.
The switching frequency is programmable from 150kHz to 300kHz.
The maximum duty cycle is 99%.
The output voltage accuracy is -1%.
The shutdown current is 20mA maximum.
The LTC1628CG#TRPBF is available in QFN and SSOP packages.
