Working Principle

The PBSS4021SN,115 is a type of bipolar transistor and works through the flow of electrons between its collector, base and emitter pins when current is applied. The PBSS4021SN,115 is a current-controlled device, wherein the current flowing through the base causes a proportional amount of current to flow through the collector-emitter. The base current amplifies the applied voltage allowing for higher current capacity and output generated from the device.

The PBSS4021SN,115 is designed for voltage regulating in synchronous buck configurations. It is designed for high efficiency and fast response time for the synchronous buck and buck-boost dc-to-dc conversions. The device offers accurate on-resistance adjustment in 24 mA or higher current level with low power dissipation. The devices includes two switch elements and two output drivers which are connected in an anti-parallel configuration. When the voltage is too low, the low side switch element (NPN) and its corresponding output driver is actuated. When the voltage is too high, the high side switch element (PNP) and its corresponding output driver is actuated.

The device exhibits a wide range of voltage ranges and high sensitivity to the applied current, which makes it suitable for various voltage regulation applications. Additionally, the PBSS4021SN,115 offers a wide dynamic response and performance enhancements such as over-temperature protection and improved start-up time due to its low input threshold.
