Supply
34713
The 34713 is a highly integrated, space efficient, low cost, single
synchronous buck switching regulator with integrated N-channel
power MOSFETs. It is a high performance point-of-load (PoL) power
supply with the ability to track an external reference voltage in
different configurations.
Its high efficient 5.0 A continuous output current capability
combined with its voltage tracking/sequencing ability and tight output
regulation, makes it ideal as a single power supply.
The 34713 offers the designer the flexibility of many control,
supervisory, and protection functions to allow for easy implementation
of complex designs. It is housed in a Pb-Free, thermally enhanced,
and space-efficient 24-Pin Exposed Pad QFN.
Features
• 45 mIntegrated N-Channel Power MOSFETs
• Input Voltage Operating Range from 3.0 V to 6.0 V
±1 % Accurate Output Voltage, Ranging from 0.7 V to 3.6 V
• Voltage Tracking Capability in different configurations.
• Programmable Switching Frequency Range from 200 kHz to
1.0 MHz with a default of 1.0 MHz
• Programmable Soft Start Timing
• Over Current Limit and Short Circuit Protection
www.DataSheet4U.com • Thermal Shutdown
• Output Overvoltage and Undervoltage Detection
• Active Low Power Good Output Signal
• Active Low Shutdown Input
• Pb-Free Packaging Designated by Suffix Code EP.

Notes
1. Continuous output current capability so long as TJ is TJ(MAX).
2. ESD1 testing is performed in accordance with the Human Body Model (CZAP=100 pF, RZAP=1500 ), ESD3 testing is performed in
accordance with the Charge Device Model (CDM).
3. The limiting factor is junction temperature, taking into account power dissipation, thermal resistance, and heatsinking.
4. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
5. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL),
Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e.
MC33xxxD enter 33xxx), and review parametrics.
