DC-DC преобразователи интегральные LM26420XMH/NOPB

Импульсный DC/DC стабилизатор , синхронный, 2 выхода, 3В - 5.5В вход, 4.5В/2А, 2.2МГц, TSSOP-20

The LM26420XMH/NOPB is a high frequency synchronous Step-down DC-DC Regulator has the ability to drive two 2A loads with an internal 75mR PMOS top switch and an internal 50mR 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 30ns, thus supporting exceptionally high-frequency conversion over the entire 3 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. It utilizes current-mode control and internal compensation to provide high performance regulation over a wide range of operating conditions. It features independent precision enables that allow the converter to be controlled by an external signal.
