Monolithic 350mA Step-Down Regulator  
Features  
• Extremely small 350mA DC/DC converter  
The EL7535 is a synchronous, integrated FET 350mA step-  
down regulator in a MSOP10 package. The regulator is  
internally compensated, which makes it possible to use just  
five tiny external components to form a complete DC/DC  
converter. The regulator operates with an input voltage  
range from 2.5V to 6V, which accommodates supplies of  
3.3V, 5V, or a Li-Ion battery source. The output can be  
• Max height 1.1mm MSOP10 package  
• Possibly uses only five tiny external components with fixed  
output  
• Power-On-Reset output (POR)  
• Internally-compensated voltage mode controller  
• Up to 94% efficiency  
externally set from 0.8V to V with a resistive divider.  
IN  
The EL7535 features PWM mode control. The operating  
frequency is typically 1.4MHz. Additional features include  
<1µA shut-down current, short-circuit protection, and over-  
temperature protection.  
• <1µA shut-down current  
• Overcurrent and over-temperature protection  
• Pb-Free plus anneal available (RoHS compliant)  
The EL7535 is available in the 10-pin MSOP package and is  
specified for operation over the full -40°C to +85°C  
temperature range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free  
material sets; molding compounds/die attach materials and 100%  
matte tin plate termination finish, which are RoHS compliant and  
compatible with both SnPb and Pb-free soldering operations. Intersil  
Pb-free products are MSL classified at Pb-free peak reflow  
temperatures that meet or exceed the Pb-free requirements of  
IPC/JEDEC J STD-020.
