SC1548 - Linear Fet Controller

Datasheet Summary

Description

The SC1548 is a power supply controller designed to provide a simple single regulated power supply with over current protection.

It is part of Semtech’s SmartLDO™ family of products.

The SC1548 can provide a 1.818V power supply for the I/O plane or 1.515V for GTL+ / AGP from either 3.3V or 2.5V.

Features

  • include tight output voltage regulation, an enable control and over current protection. Over current protection is provided by feedback to the sense pin. If the output drops below 50% of the nominal output voltage (typical) for greater than 4ms (typical), the output will be shut down. The SC1548 is available in a tiny 5-pin SOT-23 surface mount package. SC1548 Features u ± 2.5% output accuracy over line, load and u 1.515V, 1.818V and adjustable output voltage u Enable control u Over current pr.

Linear Fet Controller POWER MANAGEMENT Description The SC1548 is a power supply controller designed to provide a simple single regulated power supply with over current protection. It is part of Semtech’s SmartLDO™ family of products. The SC1548 can provide a 1.818V power supply for the I/O plane or 1.515V for GTL+ / AGP from either 3.3V or 2.5V. An adjustable option allows generation and control of any voltage from 1.263V up to 5V. SC1548 features include tight output voltage regulation, an enable control and over current protection. Over current protection is provided by feedback to the sense pin. If the output drops below 50% of the nominal output voltage (typical) for greater than 4ms (typical), the output will be shut down.
