Fairchild Semiconductor's LED driver drives OSRAM's LED products

OSRAM deploys Fairchild Semiconductor's FSEZ1016A, a new energy efficient LED driver solution into its 1W-4W LED products.

The FSEZ1016A is a high-integrated PWM controller that enables simplified circuit design for battery-charger applications such as cellular pones, cordless phones, PDA, digital cameras, and power tools.

FSEZ1016A startup current is only 10µA, which allows large startup resistance for power saving.

The key features of the FSEZ1016A controller are,

Constant-Voltage (CV) and Constant-Current (CC) Control without secondary-feedback circuitry
Fixed PWM frequency at 42kHz with frequency hopping to solve EMI problems
3.5mA of low operating current
Cycle-by-Cycle current limiting
VDD Over-Voltage Protection (OVP) with auto-restart
VDD Under-Voltage Lockout (UVLO)
Fixed Over-Temperature Protection (OTP) with latch

"We worked closely with OSRAM's engineers, based at the company's LED R&D facilities in China, and frequently discussed the technical details with OSRAM in our efforts to ensure that the FSEZ1016A was the industry's leading LED driver solution," said Benjamin Tan, Fairchild's regional vice president of Sales and Marketing, China and South East Asia.

"The FSEZ1016A is an excellent example of the value of Fairchild's Global Power ResourceSM (GPR)," continued Tan. "We use regional centers staffed by power engineers and FAEs, who are tasked with providing on-the-spot design assistance. Our GPRs are widely recognized as the industry standard for customer design support."

OSRAM says, it is also deploying Fairchild's FAN6300 LED driver for its 12W to 60W products.
