LM5642MTCX/NOPB - TI Function Overview

DESCRIPTION
The LM5642 series consists of two current mode synchronous buck regulator controllers operating 180° out of phase with each other at a normal switching frequency of 200kHz for the LM5642 and at
375kHz for the LM5642X.
FEATURES
• Two Synchronous Buck Regulators
• 180° Out of Phase Operation
• 200 kHz Fixed Nominal Frequency: LM5642
• 375 kHz Fixed Nominal Frequency: LM5642X
• Synchronizable Switching Frequency from 150 kHz to 250 kHz for the LM5642 and 200 kHz to
500 kHz for the LM5642X
• 4.5V to 36V Input Range
• 50 µA Shutdown Current
• Adjustable Output from 1.3V to 90% of Vin
• 0.04% (Typical) Line and Load Regulation Accuracy
• Current Mode Control with or without a Sense Resistor
• Independent Enable/Soft-start Pins Allow Simple Sequential Startup Configuration.
• Adjustable Cycle-by-cycle Current Limit
• Input Under-voltage Lockout
• Output Over-voltage Latch Protection
• Output Under-voltage Protection with Delay
• Thermal Shutdown
• Self Discharge of Output Capacitors when the Regulator is OFF
• TSSOP and HTSSOP (Exposed PAD) Packages
