Introduction

AI Translation

The LM25118-Q1 wide-voltage range buck/boost switching regulator controller has all the features required to implement a high-performance and cost-effective buck/boost regulator with a minimum number of external components. The buck/boost topology allows the output voltage to remain stable when the input voltage is lower or higher than the output voltage. Therefore, this device is well-suited for automotive applications. When the input voltage is sufficiently higher than the regulated output voltage, the LM25118 operates as a buck regulator and then gradually transitions to the corresponding buck/boost mode as the input voltage approaches the output voltage. This dual-mode approach maintains regulation over a wide input voltage range, provides optimal conversion efficiency in buck mode, and offers glitch-free output during mode transitions. This controller is easy to use and includes drivers for the high-side buck MOSFET and the low-side boost MOSFET. The control method of this regulator is based on current-mode control with an emulated current ramp. Emulated current-mode control reduces the noise sensitivity of the pulse-width modulation circuit to reliably control the very small duty cycles required in high-input-voltage applications. Additional protection features include current limit, thermal shutdown, and an enable input. The device is available in a power-enhanced 20-pin HTSSOP package with an exposed die-attach pad for enhanced thermal dissipation.
