SC8002 DATASHEET
SOUTHCHIP SEMICONDUCTOR TECHNOLOGY (SHANGHAI) CO.,LTD SOUTHCHIP CONFIDENTIAL
High Efficiency Buck Controller with Constant Power Limit
1 Description 2 Features
The SC8002 is a synchronous buck controller with a • Wide input operating voltage from 4.6V to 36V
wide input voltage from 4.6V to 36V. It can be
• Almost 100% duty cycle operation
configured as dual-outputs or single output. The
SC8002 regulates the output voltage at a fixed 5V or • EN for enable logic input
customized voltage by setting the divider resistor. It • Low quiescent current
also provides high accurate output current limit. The
• Programmable peak current limit
SC8002 enters Constant Current (CC) Mode in case
any of the two output channels reaches the setting • Programmable output power limit
current limit. The total output power can be • PFM and PWM mode selection
programmed by a resistor, which makes it easy for
• Build-in line drop compensation
constant power control.
• Adjustable frequency 80kHz to 600kHz
The SC8002 adopts frequency setting and operating
modes selection for PWM and PFM mode. With • Hiccup and auto-restart
minimum external components, maximum functions
• Full protection of UVLO,
