L5973D Product Details
L5973D Description
The STMicroelectronics L5973D is a step-down monolithic power switching regulator with a minimum switch current limit of 2.5 A, allowing it to provide more than 2 A DC current to the load depending on the application conditions. The L5973D uses an internal P-Channel D-MOS transistor (with a type of 200 m?) as a switching element to avoid the use of a bootstrap capacitor and guarantee high efficiency.
L5973D Features
Zero loads current operation
Internal current limiting
Inhibit for zero current consumption
Output voltage adjustable from 1.235 V to 35 V
Low dropout operation: 100 % duty cycle
250 kHz internally fixed frequency
Voltage feedforwardSynchronization
2.5 A internal switch
Operating input voltage from 4 V to 36 V
3.3 V / (±2%) reference voltage
Synchronization
Protection against feedback disconnection
Thermal shutdown
L5973D Applications
Networking: XDSL, modems, DC-DC modules
Computer: printers, audio/graphic cards, optical storage, hard disk drive
Consumer: STB, DVD, TV, VCR, car radio, LCD monitors
Industrial: changers, car battery, DC-DC converters
