The TC7660SEJA is a highly efficient DC-DC switching regulator designed to reduce the power consumption and minimize the heat generation of devices while providing the necessary power requirements. The device is applicable to applications such as car audio, lighting, measuring instruments, battery chargers, industrial control and robotics. It is also suitable for home appliances, mobile phones and laptop/desktop computing applications.
The TC7660SEJA is a dual-channel device with two channels capable of providing an adjustable output voltage from 3.0V to 5.0V. It also offers an adjustable output current up to 500mA on both channels. The device utilizes an N-channel MOSFET operating in the continuous conduction mode (CCM), which reduces switching losses and increases efficiency.
The TC7660SEJA uses a current-mode pulse-width modulation (PWM) controller that operates optimally over a wide range of input and output conditions. Its switching frequency is adjustable from 200kHz to 600kHz, allowing for a fast response to load transients. Additionally, the PFET switch is designed with a valley current protection circuit that protects the MOSFET against overcurrent conditions.
The TC7660SEJA features an adjustable soft-start function that regulates the output voltage and current during startup, ensuring stability and optimal performance. The device also has over-temperature, over-current and short-circuit protection circuits that protect it from damage during adverse operating conditions.
The TC7660SEJA features excellent efficiency, allowing it to reduce power consumption and minimize heat output. The switching frequency is adjustable, enabling a fast response to load transients. It also has over-temperature, over-current and short-circuit protection circuits for enhanced reliability. The device is highly applicable to industries such as car audio, lighting, measuring instruments, battery chargers and industrial control.
