Product Introduction
MORNSUN has just released latest IC, SCM13xxA series, which include SCM1301ATA (1A output) and SCM1316AFA (6A output), these two step-down buck ICs can meet multiple application requirements with high reliability and cost-effectiveness.
SCM1301ATA is an asynchronous rectified DC / DC buck IC with output current up to 1A.
● The wide input voltage range is from 4.5V ~ 40V, which is suitable for various applications of industrial control or automotive industry.
● Ultra-low shutdown current as low as 1.6μA to prolong the battery life.
● The SCM1301A operates at 0.7MHz fixed frequency with small external components to being able to achieve low output ripple voltage.
● Multiple protections improve system reliability, such as over-current, short-circuit and over-thermal protection.
● Integrated soft-start and compensation circuit reduces layout area and system cost by reducing external devices.
SCM1316AFA is a synchronous rectified DC / DC buck IC with frequency-jittering and average circuit mode control function.
● The SCM1316AFA has dual-channel CC / CV mode, which can provide continuous current up to 6A, and has excellent linearity and load adjustment capabilities.
● The input voltage range is from 7V to 38V and an adjustable output voltage is from 1V to 25V.
● The SCM1316AFA features over-current, short-circuit and over-thermal protection circuits to improve system reliability.
● Integrated soft-start and compensation circuit reduces layout area and system cost by reducing external devices, and the internal soft-start avoids input inrush current during startup.
Product application
It can be widely used in intelligent instrument, car charger, rechargeable portable devices and Industrial distributed power applications.
