Input voltage range up to 40V
Requires only 4 external components
150 kHz fixed frequency internal
oscillator
TTL shutdown capability
Low power standby mode,
IQ typically 85 µA
High efficiency
Thermal shutdown and current
limit protection
● Application
Simple high-efficiency step-down
(buck) regulator
LCD switching regulators
● Pin Configuration
The AE1501 series of regulators are monolithic
integrated circuits that provide all the active functions
for a step-down (buck) switching regulator, capable
of driving a 3A load with excellent line and load
regulation. These devices are available in fixed
output voltages of 3.3V, 5V version.
Requiring a minimum number of external
components, these regulators are simple to use and
include internal frequency compensation, and a fixed
frequency oscillator.
The AE1501 series operates at a switching
frequency of 150 kHz thus allowing smaller sized
filter components than what would be needed with
lower frequency switching regulators. Available in a
5-lead TO-263 surface mount package.
Other features include a guaranteed ±5%
tolerance on output voltage under specified input
voltage and output load conditions, and±15% on the
oscillator frequency. External shutdown is included,
featuring typically 85µA standby current.
Selfprotection features include a two stage frequency
reducing current limit for the output switch and an
over temperature shutdown for complete protection
under fault conditions.
