TEXAS INSTRUMENTS
The LM5118MH/NOPB is a wide voltage range Buck-Boost Switching Regulator Controller features all of the functions necessary to implement a high performance, cost efficient Buck-Boost regulator using a minimum of external components. The Buck-Boost topology maintains output voltage regulation when the input voltage is either less than or greater than the output voltage, making it especially suitable for automotive applications. The LM5118 operates as a buck regulator while the input voltage is sufficiently greater than the regulated output voltage and gradually transitions to the buck-boost mode as the input voltage approaches the output. This dual mode approach maintains regulation over a wide range of input voltages with optimal conversion efficiency in the buck mode and a glitch-free output during mode transitions. This easy-to-use controller includes drivers for the high side buck MOSFET and the low side boost MOSFET. Emulated peak current mode control Smooth transition between step-down and step-up modes Oscillator synchronization capability Internal high voltage bias regulator Integrated high and low-side gate drivers Programmable soft-start time Ultralow shutdown current Enable input wide bandwidth error amplifier 1.5% Feedback reference accuracy Thermal shutdown Green product and no Sb/Br Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
