LM26420/LM26420-Q0/Q1 Dual 2-A Automotive-Qualified, High-Efficiency Synchronous  
DC-DC Converter  
1 Features  
3 Description  
The LM26420 regulator is  
a monolithic, high-  
1
Input Voltage Range of 3 V to 5.5 V  
Output Voltage Range of 0.8 V to 4.5 V  
2-A Output Current per Regulator  
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.  
High Switching Frequency: 2.2 MHz (LM26420X)  
0.55 MHz (LM26420Y)  
0.8 V, 1.5% Internal Voltage Reference  
Internal Soft-start  
Independent Power Good and Precision Enable  
for Each Output  
Current Mode, PWM Operation  
Thermal Shutdown  
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.  
Overvoltage Protection  
Start-up into Pre-biased Output Loads  
Regulators are 180° Out of Phase  
LM26420-Q0: AEC-Q100 Grade 0 (Q0) Qualified  
(TJ = –40°C to 150°C)  
LM26420-Q1: AEC-Q100 Grade 1 (Q1) Qualified
