LM2735/LM2735Q  
520kHz/1.6MHz – Space-Efficient Boost and SEPIC DC-DC  
Regulator  
General Description  
Features  
The LM2735 is an easy-to-use, space-efficient 2.1A low-side  
switch regulator ideal for Boost and SEPIC DC-DC regulation.  
It provides all the active functions to provide local DC/DC  
conversion with fast-transient response and accurate regula-  
tion in the smallest PCB area. Switching frequency is inter-  
nally set to either 520kHz or 1.6MHz, allowing the use of  
extremely small surface mount inductor and chip capacitors  
while providing efficiencies up to 90%. Current-mode control  
and internal compensation provide ease-of-use, minimal  
component count, and high-performance regulation over a  
wide range of operating conditions. External shutdown fea-  
tures an ultra-low standby current of 80 nA ideal for portable  
applications. Tiny SOT23-5, LLP-6, and eMSOP-8 packages  
provide space-savings. Additional features include internal  
soft-start, circuitry to reduce inrush current, pulse-by-pulse  
current limit, and thermal shutdown.  
Input voltage range 2.7V to 5.5V  
Output voltage range 3V to 24V  
2.1A switch current over full temperature range  
Current-Mode control  
Logic high enable pin  
Ultra low standby current of 80 nA in shutdown  
170 mNMOS switch  
±2% feedback voltage accuracy  
Ease-of-use, small total solution size  
Internal soft-start  
Internal compensation  
Two switching frequencies  
520 kHz (LM2735-Y)  
1.6 MHz (LM2735-X)  
Uses small surface mount inductors and chip capacitors  
Tiny SOT23-5, LLP-6, and eMSOP-8 packages  
LM2735Q is AEC-Q100 Grade 1 qualified and is  
manufactured on an Automotive Grade Flow
