Monolithic 600mA Step-Down Regulator  
with Low Quiescent Current  
Features  
2
• Less than 0.18in footprint for the complete 600mA  
converter  
The EL7530 is a synchronous, integrated FET 600mA 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 Li-Ion battery source. The output can  
• Components on one side of PCB  
• Max height 1.1mm MSOP10  
be externally set from 0.8V to V with a resistive divider.  
IN  
• Power-Good (PG) output  
The EL7530 features automatic PFM/PWM mode control, or  
PWM mode only. The PWM frequency is typically 1.4MHz  
and can be synchronized up to 12MHz. The typical no load  
quiescent current is only 120µA. Additional features include  
a Power-Good output, <1µA shut-down current, short-circuit  
protection, and over-temperature protection.  
• Internally-compensated voltage mode controller  
• Up to 95% efficiency  
• <1µA shut-down current  
• 120µA quiescent current  
• Overcurrent and over-temperature protection  
• External synchronizable up to 12MHz  
• Pb-free plus anneal available (RoHS compliant)  
The EL7530 is available in the 10 Ld MSOP package,  
2
making the entire converter occupy less than 0.18n of PCB  
area with components on one side only. The 10 Ld MSOP  
package 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.
