3 Description

The LM26420 regulator is a monolithic, high- efficiency dual PWM step-down DC/DC converter. This device has the ability to drive two 2-A loads with an internal 75-mΩ PMOS top switch and an internal 50-mΩ NMOS 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 30 ns, thus supporting exceptionally high-frequency conversion over the entire 3-V to 5.5- V input operating range down to the minimum output voltage of 0.8 V.

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 utilizes current-mode control and internal compensation to provide high performance regulation over a wide range of operating conditions.
