User's Guide SNVA651A – May 2012 – Revised May 2013 AN-2233 TPS92311 Evaluation Module 1 Introduction The TPS92311 EVM-8W evaluation module is a constant current output LED driver supporting 5W–8W applications. The design focuses on applications that require small form factor and minimal number of external components. The actual PCB dimension of the module is only 22mm x 55mm x 19mm (L x W x H). The module can work with AC line input from 90 to 132VRMS or 180 to 264VRMS and supplying 350mA current into a single string of LEDs, typically 6-7 LEDs in series. The evaluation board is carefully designed to comply with major industrial EMC and safety requirements. The user can make use of the information provided in the TPS92311 Off-Line Primary Side Sensing Converter with PFC (SNVS811) data sheet and application notes to design its specific end product easily. 2 Description The TPS92311 EVM-8W is developed with the TPS92311 converter IC. The TPS92311 is a single-stage AC/DC converter dedicated for LED Lighting applications. The converter uses a primary-side current sense configuration to control the LED current at secondly side. The system works in Critical Conduction Mode (CRM) with flyback topology and it employs a constant on time modulation scheme. Inherently, systems with this configuration can achieve greater than 0.90 Power Factor (PF) easily. The Power Factor (PF) and line current harmonic performances of the evaluation board are tested and reported in this document. The TPS92311 also integrated various protection features: Over-Voltage Protection (OVP), Thermal Shut Down (TSD) and cycle-by-cycle Over-Current Protection (OCP). With these features in place, the system is well protected against open and short circuit of the LEDs string. Considering with the EMI problem, the TPS92311 integrates an internal delay timer to improve it. The delay time can be programmed through an external resistor, it can ensures the converter switch ON the internal MOSFET only when the MOSFET’s drain voltage at its lowest point. The Quasi-resonant switching operation improves the EMI and system efficiency significantly. 3 Typical Applications LED Lamps: • A19 (E26/27, E14) • PAR30/38 • GU10 Domestic and Office SSL solutions: • Down Light • LED Panel Light • Ceiling Lamp Troffer • T8 Tube All trademarks are the property of their respective owners.
