LTC3728LXCUH Description

Short technical summary and product information.

The LTC3728LXCUH is a dual, 550kHz, 2-phase synchronous switching regulator controller manufactured by Linear Technology (LT). This component is designed for high-performance power supply applications, offering features such as OPTI-LOOP® compensation for minimized output capacitance and ±1% output voltage accuracy (on specific variants like LTC3728LC).

 

Key electrical specifications include a wide input voltage range from 4.5V to 28V, with output voltages adjustable from 0.8V up to 7V. It supports a high output current of 25A and a switch current of 25A. The device operates at a nominal frequency of 550kHz, with a phase-lockable frequency sync range of 250kHz to 500kHz. It also features low shutdown current of 20µA.

 

Available in 5mm x 5mm QFN-32 and 28-lead narrow SSOP packages, the LTC3728LXCUH is suitable for applications such as notebook and palmtop computers. Its dual, 180° phased controllers help reduce input capacitance and power supply induced noise. The device also includes a Power Good output voltage indicator and supports multiple operating modes including Constant-Frequency, Burst Mode®, and PWM.
