Monolithic 600mA Step-Down Regulator  
Features

The EL7534 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  
• Less than 0.15 in (0.97 cm ) footprint for the complete  
600mA converter  
• Components on one side of PCB  
• Max height 1.1 mm MSOP10  
accommodates supplies of 3.3V, 5V, or a Li-Ion battery  
source. The output can be externally set from 0.8V to V  
with a resistive divider.  
IN  
• 100ms Power-On-Reset output (POR)  
• Internally-compensated voltage mode controller  
• Up to 94% efficiency  
The EL7534 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  
• Overcurrent and over-temperature protection  
• Pb-free plus anneal available (RoHS compliant)  
The EL7534 is available in the 10 Ld MSOP package,  
making the entire converter occupy less than 0.15 in of  
PCB area with components on one side only. Both packages  
are 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.
