FEATURES  
DESCRIPTION  
The LMR61428 is  
a step-up DC-DC switching  
23  
1.2V to 14V Input Voltage  
regulator for battery-powered and low input voltage  
systems that can achieve efficiencies up to 90%. It  
has a wide input voltage range from 1.2V to 14V and  
a possible regulated output voltage range of 1.24V to  
14V. It has an internal 0.17Ω N-Channel MOSFET  
power switch.  
Adjustable Output Voltage up to 14V  
Switch Current up to 2.85A  
Up to 2 MHz Switching Frequency  
Low Shutdown Iq, <1µA  
Cycle-by-Cycle Current Limiting  
VSSOP Packaging (3.0 x 5.0 x 1.09mm)  
WEBENCH® Enabled  
The high switching frequency of up to 2MHz of the  
LMR61428 allows for tiny surface mount inductors  
and capacitors. Because of the unique constant-duty-  
cycle gated oscillator topology very high efficiencies  
are realized over a wide load range. The supply  
current is reduced to 80µA because of the BiCMOS  
process technology. In the shutdown mode, the  
supply current is less than 2.5µA. The LMR61428 is  
available in a VSSOP-8 package.  
PERFORMANCE BENEFITS  
Extremely Easy to Use  
Tiny Overall Solution Reduces System Cost  
APPLICATIONS  
Boost/SEPIC Conversions from 3.3V, 5V, and  
12V  
Space Constrained Applications  
LCD Displays  
LED Applications
