Supertex, Inc today introduced HV9803, an open loop, average-mode, current control LED driver IC operating in a constant off-time mode. It is well suited for backlighting LCD panel applications such as TVs and monitors.

Supertex today introduced the HV7350, an eight channel, monolithic, high-voltage, high-speed, pulse generator IC with built-in fast return-to-zero (RTZ) damping FETs is designed for portable medical diagnostic ultrasound applications.

Supertex, Inc. has introduced CL220, a high voltage, temperature-compensated, constant current, LED driver integrated circuit (IC). It is designed to drive a string of LEDs with a constant current of 20mA, and multiple ICs can be used in parallel to provide higher output currents in increments of 20mA. It can be used in a variety of solid-state lighting applications, such as signage, automotive, industrial indicators and accent lighting.

Supertex, Inc. has introduced HV9801A, a power saving, switch dimmable, LED driver integrated circuit (IC) designed to drive LEDs in dimmable household and office lighting applications. The IC dims LED lamp brightness to one of four preset levels through simple, rapid toggling of a light switch. Light levels progress up and down sequentially and if the switch is turned off for more than a second, the lamp returns to full brightness.

Supertex, Inc. has introduced the HV9861A, an open loop, average current mode control, LED driver integrated circuit (IC) designed to drive LEDs using a buck topology. It is well suited for a variety of solid-state lighting applications, including TV and monitor backlighting, signage, decorative, and general lighting.

Supertex, Inc today introduced AT9919, an LED lamp driver integrated circuit, designed specifically for solid-state lighting applications in automobiles, such as head lights, tail lights, brake indicator lights, dome lights, and panel backlights. AT9919 is AEC-Q100 compliant, and drives LEDs using a buck topology. It is available in a compact, eight-lead, DFN package.
