GL2596
3A STEP-DOWN VOLTAGE REGULATOR
Description
GL2596 of regulators provides all the active functions for a
step-down (buck) switching regulator, and drives 3A load
with excellent line and load regulation. GL2596's is
available in fixed output voltages of 3.3V, 5V, 12V, and a
versatile Adjustable output version.
These regulators are simple to use and require a minimum
number of external components. Features include internal
frequency compensation and a fixed-frequency oscillator.
The GL2596 is high-efficiency replacements for popular
three-terminal linear regulators, and is requiring a smaller
heatsink or even no heatsink.
GL2596 performs well with standard inductors from
several manufacturers, and simplifying the design of
switch-mode power supplies.GL2596 guarantees 4%
tolerance on output voltage within specified input
voltages and output load conditions, and 15% on the
oscillator frequency.
Features
3.3V, 5V, 12V and Adjustable output versions
Adjustable version output voltage range 1.23V
to 37V 4% max over line and load conditions
3A output current
Input voltage range up to 40V
Requires only 4 external components
High efficiency
TTL shutdown capability
Low power standby mode, IQ typically 100 μA
Thermal shutdown, current limit protection
Uses standard inductors
150 kHz fixed frequency internal oscillator
External shutdown is included with 100uA (typical)
standby current. The output switch has cycle-by-cycle
current limiting as well as thermal shutdown for full
protection under fault conditions.
GL2596 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 and DFN-8 package.
Application
Pre-regulator for linear regulators
On-card/board switching regulators
High-efficiency step-down buck regulator Positive to negative converter (buck-boost)
