This reference design delivers a high efficiency LED driver circuit with dimming function using the boost converter TPS61021A. The PWM dimming method can be used in one or two cell AA battery input applications, and the analog dimming method can be used in one cell AA battery input applications. PMP15037 can realize the dimming function through the addition of several resistors and one MOSFET into the circuit, making it an cost-effective and high efficiency solution for LED driver applications.

Automotive 12V batteries typically operate in the range of 9V-16V. However this voltage can vary widely due to transient conditions such as cold crank and load dump. This reference design creates a well-regulated 25W (5V,5A) output, regardless of large input voltage transients, utilizing the LM5150-Q1 and LM5141-Q1. The LM5150-Q1 is implemented as a pre-boost, only switching when the input voltage is below 6.8V, and utilizes the inductor as a differential EMI filter when not switching. The LM5141-Q1 operates as a buck controller regulating the 5V output. Both devices switch at 2.2 MHz.
