P2576/HV
LINEAR INTEGRATED CIRCUIT
3A STEP-DOWN VOLTAGE
SWITCHING REGULATOR
DESCRIPTION
As a step-down (buck) switching regulator, the UTC
P2576/HV provides drives 3A load. The UTC P2576/HV are
simple because it only needs to use a minimum number of
external components.
Frequency compensation and a fixes-frequency oscillator are
in it. UTC P2576/HV can perform with standard inductors, and
simplifying the switch mode power supplies’ design. UTC
P2576/HV guarantees output load conditions and ±10% on the
oscillator frequency. Its external shutdown is included with 50μA
standby current. As well as thermal shutdown for full protection
under fault conditions, the output switch has cycle by cycle
current limiting.
FEATURES
* Output Current 3A
* Input Voltage Range of 7V to 40V for P2576 and 7V to 60V for
P2576HV
* Requires 4 External Components
* Very High Efficiency
* TTL Shutdown
* Low Power Standby Mode
* Thermal Shutdown,
* Current Limit Protection
* Internal Oscillator: 52 kHz Fixed Frequency
