EL7530
FN7434.1
Monolithic 600mA Step-Down Regulator
with Low Quiescent Current
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 be externally set from 0.8V to
VIN with a resistive divider.
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.
Features
• Less than 0.15in2 (0.97cm2) footprint for the complete
600mA converter
• Components on one side of PCB
• Max height 1.1mm MSOP10 or 1mm DFN 10 package
• Power-Good (PG) output
• Internally-compensated voltage mode controller
• Up to 95% efficiency
• <1µA shut-down current
• 120µA quiescent current
• Over-current and over-temperature protection
• External synchronizable up to 12MHz
The EL7530 is available in the 10-pin MSOP and 10-pin
DFN (3x3mm) packages, making the the entire converter
occupy less than 0.15in2 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.
