Analog Devices LT3799EMSE-1 | Demoboard DC1947A
LT3799EMSE-1 Demo Board u Offline Isolated Flyback LED Driver with PFC
Overview
| Topology | Flyback Converter |
| Input voltage | 90-277 V |
| Output 1 | 48 V / 1 A |
| IC revision | 2 |
Description
Demonstration circuit 1947A is an off-line isolated flyback LED driver featuring LTC®3799-1 . The demo board provides a single constant current output of 1A over an LED string voltage from 30V to 50V. It is optimized to operate over a wide AC input voltage range (90VAC to 277VAC, 47Hz to63Hz). It provides a high power factor (>0.9) enabling a single design to be used worldwide. It is also designed to comply with the IEC 61000-3-2 Class C harmonics standard and the EN55015B conducted EMI standard.
The LT3799-1 controls an isolated flyback converter in boundary mode. Its novel current sensing scheme delivers a well-regulated output current to the secondary side without using an opto-coupler. Open- and shorted-LEDprotection ensures long term reliability.
The LT3799-1 is available in a low profile, thermallyenhanced 16-lead MSOP package.
The LT3799-1 data sheet gives a complete description of the device, operation and application information. The data sheet must be read in conjunction with this quick start guide for demo circuit 1947A.
