LM21215A Description
The LM21215A is a synchronous buck DC-DC converter that delivers up to 15 A of output current at output voltages as low as 0.6 V. Operating over an input voltage range of 2.95 V to 5.5 V with ultra-high efficiency, the LM21215A suits a wide variety of low voltage systems. The voltage-mode control loop with high gain-bandwidth error amplifier provides high noise immunity, narrow duty cycle capability and is easily...
