Employing accurate primary side power regulation, the IRS29831 integrates an LED driver control IC and power MOSFET utilizing 700V technology and features high-voltage start up to offer a simple cost-effective single stage solution while maintaining a high power factor and low Total Harmonic Distortion (THD) for improved efficiency.
“The IRS29831 provides an extremely competitive and efficient solution for both isolated and non-isolated Flyback LED drivers. The device offers single stage primary side regulation with a high power factor and low Total Harmonic Distortion (THD) along with open and short circuit protection.” said Peter Green, LED Group Manager, IR’s Energy Saving Products Business Unit.
IRS29831-based LED driver circuits also offer smooth, flicker-free dimming with triac based dimmers. The device can also operate over a wide input voltage range. Protection features include hiccup mode open-load/over-voltage protection, cycle-by-cycle primary over current limiting, and output short circuit protection.
The IRS29831 also features critical-conduction mode operation, with discontinuous and burst modes at light load as well as the ability to allow users to configure isolated designs without an opto-coupler. Available in an 8-pin DIP package, the IRS29831 has a fast startup, low quiescent current, ESD protection and noise immunity.
