Monolithic 2A Step-Down Regulator  
Features  
• 2A continuous current (from -40°C to +85°C)  
The EL7532 is a synchronous, integrated FET 2A step-down  
regulator with internal compensation. It operates with an  
input voltage range from 2.5V to 5.5V, which accommodates  
supplies of 3.3V, 5V, or a single Li-Ion battery source. The

• Less than 0.18 in footprint for the complete 2A converter  
• Max height 1.1mm MSOP10  
output can be externally set from 0.8V to V with a resistive  
IN  
• 1.5MHz (typ.) switching frequency  
• 100ms Power-On-Reset output (POR)  
• Internally-compensated voltage mode controller  
• Up to 94% efficiency  
divider.  
The EL7532 features PWM mode control. The operating  
frequency is typically 1.5MHz. Additional features include a  
100ms Power-On-Reset output, <1µA shut-down current,  
short-circuit protection, and over-temperature protection.  
• <1µA shut-down current  
The EL7532 is available in the 10-pin MSOP package,  
making the entire converter occupy less than 0.18 in of  
PCB area with components on one side only. The package is  
specified for operation over the full -40°C to +85°C  
temperature range.  
• Overcurrent and over temperature protection  
• Pb-Free plus anneal available (RoHS compliant)

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.
