Monolithic 350mA Step-Down Regulator
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
externally set from 0.8V to V
IN
with a resistive divider.
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.
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.
Features
• Extremely small 350mA DC/DC converter
• 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
• <1µA shut-down current
• Overcurrent and over-temperature protection
• Pb-Free plus anneal available (RoHS compliant)
Applications
• PDA and pocket PC computers
• Bar code readers

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.
