150 V – 150 W LED driver using the STCMB1 transition mode PFC and HBR resonant tank combo controller

The growing popularity of LEDs, thanks to their high efficiency and longer lifetime, are greatly contributing to the reduction of energy consumption for internal and external lighting. Street lighting applications require a power supply specifically designed to power an LED lamp having high efficiency and a long lifetime in order to guarantee maintenance-free operation during the lifetime of the LED.

This whitepaper describes the performance of a 150 W, wide input mains range, power- factor-corrected, LED driver board. Its electrical specification is tailored to a typical high-power street lighting application.
