Description
General part information
LM26420-Q1 Series
The LM26420-Q1 regulator is a monolithic, high-efficiency dual PWM step-down DC/DC converter. This device has the ability to drive two 2A loads with an internal 75mΩ MOS top switch and an internal 50mΩ MOS bottom switch using state-of-the-art BICMOS technology results in the best power density available. The world-class control circuitry allow on times as low as 30ns, thus supporting exceptionally high-frequency conversion over the entire 3V to 5.5V input operating range down to the minimum output voltage of 0.8V.
Although the operating frequency is high, efficiencies up to 93% are easy to achieve. External shutdown is included, featuring an ultra-low standby current. The LM26420-Q1 uses current-mode control and internal compensation to provide high performance regulation over a wide range of operating conditions.
Because the switching frequency is made sure to be greater than 2MHz, the LM26420-Q1 can be used in automotive applications without causing interference in the AM frequency band.
