New Cypress Automotive LED Driver Delivers Robust Performance and Minimizes the Bill-of-Material for Headlight Systems

Small, Cost-Effective Front Lighting Solution Enables Robust Operation Even in Challenging Temperature and EMI Conditions

SAN JOSE, Calif., July 26, 2016 — (PRNewswire) —  Cypress Semiconductor Corp. (NASDAQ: CY) today introduced an automotive LED driver that enables smaller and more cost-effective headlight systems. The new S6BL112A automotive-grade LED driver is the industry's first to feature synchronous control, which helps it provide industry-leading conversion efficiency, enabling stable performance in a lighting system. The device is able to drive LEDs at a high 2.1-MHz switching frequency, which enables a compact headlight solution that uses small, inexpensive inductors, reducing physical size and bill-of-materials costs. The LED drivers combine with Cypress's Traveo™ microcontrollers (MCUs) and power management ICs (PMICs) to provide a best-in-class automotive front-lighting solution.

Pictured is the Cypress S6BL112A automotive LED driver, which enables smaller and more cost-effective headlight systems. The automotive-grade LED driver is the industry's first to feature synchronous control, delivering industry-leading conversion efficiency and stable performance in a lighting system.

Cypress's S6BL112A Automotive LED driver features an input voltage range of 4.5-42 V that encompasses extreme operating conditions such as cold-cranking—when the automobile engine starter draws an excessive amount of current due to starting the engine in cold temperatures—or load dump—a power surge that occurs when an automobile battery is disconnected while the alternator is supplying current during engine operation. The LED driver also facilitates the design of electrical system safeguards by including System Safety Functions such as under current detection, over current and voltage protection, as well as the ability to mask undesired LED OPEN diagnosis during cold cranking. Additionally, its synchronous operation eliminates unstable dimming that can occur when the input voltage is low. More information on Cypress's automotive LED drivers is available at

"With the fast-growing usage of LED lighting systems in cars and other vehicles, automotive suppliers are seeking to minimize the component count and cost in these systems without compromising on reliability or performance," said Kiyoe Nagaya, vice president of the Analog Business Unit at Cypress. "Cypress's automotive LED drivers provide a compact, efficient headlight solution, supported by our complementary automotive MCUs and PMICs, with robust performance even in extreme temperatures or when faced with disruptive electrical noise."

The S6BL112A is a one-channel 2A output Buck LED driver that supports both analog and PWM dimming functions, enabling precise brightness control. Its switching frequency can be set between 205 kHz and 2.1 MHz, with high output current accuracy of +/-2%. The device enables slew rate control without an external filter, limiting Electro Magnetic Interference (EMI) generation that can harm peripherals.

Product Availability

The new S6BL112A LED driver is currently sampling, with production expected in the fourth quarter of 2016. It is available in a 16-pin, thermally-enhanced TSSOP package.
