LM26420XSQ/NOPB-Dual 2.0A, High Frequency Synchronous Step-Down DC-DC Regulator

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.

For all available packages, see the orderable addendum at the end of the data sheet.

LM26420XSQ/NOPB双2.0A,高频同步降压型DC-DC稳压器
LM26420稳压器是单片的、高效率的双PWM降压DC-DC转换器。该设备有能力驱动两个2-A负载与内部75米ΩPMOS顶部开关和内部50-MΩNMOS底部开关使用最先进的BiCMOS技术的结果在最佳功率密度可用。世界级的控制电路允许低至30 ns的时间,从而支持在整个3-V到5.5-V输入操作范围的异常高频转换到0.8 V的最小输出电压。
虽然工作频率高,但效率高达93%容易实现。外部关机包括,具有超低待机电流。LM26420利用电流模式控制和内部补偿,以提供高性能调节在很宽的操作条件范围内。
