The LTC3728LEGN#TRPBF from LT is a dual, 180° phased controller designed for synchronous buck regulation. Operating at a fixed frequency of 550kHz, it is capable of handling input voltages from 4.5V to 28V and providing output voltages between 0.8V and 7V. This device supports dual N-channel MOSFET synchronous drive and offers features like OPTI-LOOP® compensation, power good output voltage indication, and phase-lockable frequency control.
With a very low dropout operation achieving 99% duty cycle, adjustable soft-start current ramping, and foldback output current limiting, the LTC3728LEGN#TRPBF is suitable for demanding applications. It includes latched short-circuit shutdown with defeat option and output overvoltage protection. The controller also features 5V and 3.3V standby regulators and offers three selectable operating modes: Constant-Frequency, Burst Mode® Operation, and PWM.
Packaged in a 28-lead narrow SSOP, this component is designed for applications such as notebook and palmtop computers. Its dual-phase architecture helps reduce required input capacitance and power supply induced noise.
The operating frequency is 550 kHz.
The input voltage range is 4.5V to 28V.
The output current is 25 A.
The package type is SSOP-28.
The operating temperature range is 0°C to 85°C.
