36V, 2A Monolithic Synchronous Step-Down LED Driver with Silent Switcher Topology Minimizes EMI Concerns

Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LT3932, a monolithic, synchronous, step-down DC/DC converter with internal 36V, 2A power switches and an internal PWM generator. Its fixed frequency, peak current mode control accurately regulates current within ±1.5% for strings of up to 2A LEDs. Its integrated PWM generator offers a 128:1 dimming ratio. If dimming ratios of up to 5000:1 are required, the LT3932 and an external PWM generator can accommodate these applications.
