FEATURES  
DESCRIPTION  
The LMR10530 regulator is  
a monolithic, high  
23  
Input Voltage Range of 3.0V to 5.5V  
Output Voltage Range of 0.6V to 4.5V  
frequency, PWM step-down DC/DC converter  
available in a 10-pin WSON package. It contains all  
the active functions to provide local DC/DC  
conversion with fast transient response and accurate  
regulation in the smallest possible PCB area. With a  
minimum of external components, the LMR10530 is  
easy to use. The ability to drive 3.0A loads with an  
internal 56 mPMOS switch using state-of-the-art  
0.5µm BiCMOS technology results in the best power  
density available. The control circuitry allows 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 0.6V. Switching frequency is internally set to  
1.5MHz or 3.0MHz, allowing the use of extremely  
small surface mount inductors and capacitors. Even  
though the operating frequency is high, efficiencies  
up to 93% are easy to achieve. External shutdown is  
included, featuring an ultra-low stand-by current of  
300nA. The LMR10530 utilizes peak current-mode  
control and internal compensation to provide high-  
1.5 MHz (LMR10530X) and 3 MHz (LMR10530Y)

PERFORMANCE BENEFITS  
Extremely Easy to Use  
Tiny Overall Solution Reduces System Cost  
performance regulation over  
a wide range of  
operating conditions. Additional features include  
internal soft-start circuitry to reduce inrush current,  
cycle-by-cycle current limit, frequency foldback,
