Description

The IT8510G is a highly integrated embedded controller with system functions suitable for mobile system applications. The IT8510 directly interfaces to the LPC bus and provides ACPI embedded controller function, keyboard controller (KBC) and matrix scan, external flash interface for system BIOS and EC code, PWM, ADC and SmartAuto Fan control for hardware monitor, PS/2 interface for external keyboard/mouse devices, RTC and system wake up functions for system power management. It also supports the external flash ( or EPROM) to be shared by the host and EC side.

This is a compact, self-contained computing system that is designed to perform specific tasks within a larger system. It is a key component of embedded systems, which are integrated into various devices and products to provide specific functionalities.

Description

 

The SD4842 is a current mode PWM controller with low standby power and low start current for power switch. In standby mode, the circuit enters burst mode to reduce the standby power dissipation. The switch frequency is 67KHz with ±2.5 KHz jitter frequency for low EMI.

The stress on transformer during power on is reduced by the builtin 15ms soft start circuit to avoid the saturation of transformer. SD4840/4841/4842/4843/4844 includes under voltage lock-out, over voltage protection, leading edge blanking, over current
protection and the temperature protection. The circuit will restart automatically until the system is normal after the protection is active.
