Non-isolated Dimmable LED Driver with improved line regulation

PMP4327A: This reference design demonstrates a high efficiency non-isolated dimmable LED driver solution using LM3445. With additional feed-forward circuit, improved line regulation <+/-2% performance is achieved. The input range is 90~132Vac and output is 40V310mA.

110V AC in Non-isolated Dimmiable GU10 LED Driver

PMP4389: The PMP4389 is a 110Vac input non-isolate dimmable GU10 LED driver using TPS92075. It delivers 30V120mA output with high efficiency > 81% over input range. The PF>0.97. PMP4389 demonstrates perfect compatiblity with different dimmers. The overall size is limited in 26mmx18mmx16mm. PMP4389 also passes EMI guidelines.

15 Cell Lithium Ion Battery Controller Analog Front End Reference Design

TIDA-00255: The TIDA00255 reference design utilizes the bq76940 analog front end (AFE) IC. It measures cell voltages, and die temperature or external thermistor voltage using a 14 bit ADC. Current is measured separately by a separate 16 bit coulomb counter. The design can turn off low side power FETs to stop discharge or charge based on selected hardware limits. A microcontroller not included in this design would be part of the battery controller to communicate to the AFE to set protection thresholds, turn on the power FETs, provide fault recovery and turn off the FETs for over or under temperature conditions. A battery controller design may contain other features which are not part of this reference design such as secondary over voltage protection, gauging, and isolated communication to let the system know the state of the battery.

120V AC input and 24.5V output LED Driver

PMP7770: It is an offline AC-DC LED driver. It has TRIAC dimming capability. It is basically a low side buck which has valley filled PFC. It takes an input voltage of 120V AC. This circuit uses LM3445 which is an adaptive constant off-time AC/DC buck (step-down) constant current controller designed to be compatible with Traic dimmers.

TPS92075 - 120VAC, 5W, Phase Dimmable Non-Isolated Buck PFC LED Driver

PMP8023: The main purpose of this reference design is to demonstrate a high performance and low BOM cost offline phase dimmable Buck PFC LED driver based on TPS92075. This LED driver is designed for converting an AC input to a regulated LED current. The operating conditions and performance of the reference design are as follows:

120Vac Single Stage Non-Dimmable 50W LED Driver Reference Design

PMP6017: This reference design provides a high power ( 50W ) non-isolated, non-dimming LED driver based on the TPS92074. With a nominal input of 120VAC and input range covering 108VAC to 132VAC, the design provides 1 Amp of output current to a 47V nominal stack of LEDs (~16 LEDs). The Buck PFC provides high power factor and low THD.

120Vac Non Dimmable 8W LED Driver

PMP6014: This TPS92074 reference design presents the TPS92074 controller driving a 30V string of LEDs at 250mA in a buck configuration. It is a non dimmable design.
