MAX17509 EVALUATION KIT AVAILABLE Dual 3A, High-Efficiency, Synchronous Step-Down DC-DC Converter with Resistor Programmability The MAX17509 integrates two 3A internal switch step-down regulators with programmable features. The device can be configured as two single-phase independent, 3A power supplies or as a dual-phase, single-output 6A power supply. The device operates from 4.5V to 16V input and generates independently adjustable output voltage in the ranges of 0.904V to 3.782V and 4.756V to 5.048V, with ±2% system accuracy. This device provides maximum flexibility to the end-user by allowing to choose multiple programmable options by connecting resistors to the configuration pins. Two key highlights of the device are the self-configured compensation for any output voltage and the ability to program the slew rate of LX switching nodes to mitigate noise concerns. In noise-sensitive applications, such as highspeed multi-gigabit transceivers in FPGAs, RF, and audio benefit from this unique slew rate control. SYNC input is provided for synchronized operation of multiple devices with system clocks. MAX17509 offers output overvoltage OV and undervoltage UV protection, as well as overcurrent OC and undercurrent UC protection with a selectable hiccup/latch option. It operates over the -40°C to +125°C temperature range, with thermal sensing and shutdown provided for overtemperature OT protection. The device is available in a 32-pin 5mm x 5mm TQFN package. ●● FPGA and DSP Core Power ●● Industrial Control Equipment ●● Multiple Point-of-Load POL Power Supplies ●● Base Station Point-of-Load Regulator Ordering Information appears at end of data sheet. ●● Reduces Number of DC-DC Regulators in Inventory • Output Voltage 0.904V to 3.782V and 4.756V to 5.048V with 20mV Resolution • Configurable Two Independent Outputs 3A/3A or a Dual-Phase Single Output 6A ●● Mitigate Noise Concerns and EMI • Adjustable Switching Frequency with Selectable 0/180° Phase Shift • External Frequency Synchronization • Adjustable Switching Slew Rate • Passes EN55022 CISPR22 Class-B Radiated and Conducted EMI Standard ●● Ease of System Design • All Ceramic Capacitors Solution • Auto-Configured Internal Compensation • Selectable Hiccup or Brickwall Mode • Adjustable Soft-Start Rise/Fall Time with Soft Stop Modes and Prebias Startup • -40°C to +125°C Operation ●● Reliable Operation • Robust Fault Protections VIN_UVLO, UV/OV, UC/ OC, OT • Power Good Application Circuit MAX17509 CVCC PGOOD1, 2 SYNC CAVCC AVCC RCOARSE1 COARSE1 RFINE1 FINE1 RSS1 SS1 RCOARSE2 COARSE2 RFINE2 FINE2 RSS2 SS2 RMODE MODE EN1, 2 AVCC BST1 CBST1 LX1 OUT1 PGND1 BST2 CBST2 LX2 OUT2 PGND2 VIN CIN1 VOUT1 COUT1 VIN CIN2 VOUT2 COUT2 SGND EP MAX17509 Dual 3A, High-Efficiency, Synchronous Step-Down DC-DC Converter with Resistor Programmability Absolute Maximum Ratings IN_ to 22V BST_ to 28V BST_ to 6V BST_ to 22V LX_ to PGND_....... -0.3V to the lower of +22V or VIN_ + 0.3V VCC to SGND.......... -0.3V to the lower of +6V or VIN1 + 0.3V AVCC to SGND........ -0.3V to the lower of +6V or VIN1 + 0.3V OUT_, EN_, PGOOD_, SYNC, COARSE_, FINE_, SS_, MODE to 6V PGND_ to 0.3V EP to +0.3V Operating Temperature Range...........................-40ºC to +125ºC Junction Storage Temperature to +160°C Lead Temperature soldering, 10s .................................. +300°C Soldering Temperature Package Thermal Characteristics Note 2 32 TQFN T3255+4 Continuous Power Dissipation TA = +70°C 32 TQFN derate mW/°C above +70°C multilayer board Junction-to-Ambient Thermal Resistance 32 Ordering Information PART TEMP RANGE PIN-PACKAGE MAX17509ATJ+ -40ºC to +125ºC 32 TQFN-EP* +Denotes a lead Pb -free/RoHS-compliant package. *EP = Exposed paddle.
