TCP8510升降压芯片采用QFN4x4-24L封装,是单电感4管驱动Buck-Boost 控制器,输入电压范围4.5V-40V ,可调开关频率高达1MHz,可编程外部软启动时间,故障后自动恢复 ,VBUS线电压降补偿,具有PG信号输出, 可编程过流保护、过电压保护、过温保护。同时成绎半导体可提供CHC6380+TCP8510完整的PD车充方案。
The TCP8510 is a four-switch buck-boost controller IC with integrated drivers for N-channel MOSFETs. TCP8510 operates in the buck mode when VIN is greater than VOUT, in the boost mode when VIN is less than VOUT, and in the buck-boost mode when VIN is close to VOUT.
The TCP8510 integrates four N-Channel MOSFET drivers including two low-side drivers and two high-side drivers, eliminating the need for external drivers or floating bias supplies. The internal VCC regulator supplies internal bias rails as well as the MOSFET gate drivers.
The PWM control scheme is based on valley current mode control for buck operation and peak current mode control for boost operation. The inductor current is sensed through a single sense resistor to ground in series with the low side MOSFETs. The sensed current is also monitored for cycle-by-cycle current limit.
In addition to the cycle-by-cycle current limiting, the TCP8510 also provides output current regulation that can be configured for output current limiting and short circuit protection. This is useful for battery charging or other applications where a constant current behavior may be required.
The soft-start time of TCP8510 is programmed by a capacitor connected to the SS pin to minimize the inrush current and overshoot during startup. The EN/UVLO pin supports programmable input under voltage lockout (UVLO) with hysteresis. The PG output indicates when the FB voltage is inside a±10% regulation window centered at VREF.
