Evaluates: MAX5072 19-3603 Rev 0 3/05 MAX5072 Evaluation Kit General Description Features The MAX5072 evaluation kit (EV kit) is a fully assembled 5.5V to 16V Input Supply Voltage Range and tested circuit board that contains all the components 4.5V to 5.5V Input Supply Voltage Range necessary to evaluate the performance of the MAX5072. (Configurable) The MAX5072 is a dual-output DC-DC converter. One of the outputs is configured as a step-down converter (con- 3.3V at 2A Output (Step-Down Converter) verter 1), while converter 2 is configured as a step-up 12V at 0.22A Output (Step-Up Converter) converter. The EV kit is powered from a DC supply pro- viding 5.5V to 16V. The EV kit can be reconfigured for an 180 Out-of-Phase Operation Reduces Input input voltage range between 4.5V to 5.5V. Capacitance The MAX5072 EV kit is capable of delivering 3.3V at 2A Clock Output for Four-Phase Operation from the step-down converter output and 12V at up to 0.22A from the step-up converter output. The MAX5072 Programmable Switching Frequency (200kHz to switching frequency is set to 2.2MHz and the two out- 2.2MHz) puts switch 180 out of phase. A SYNC input facilitates Individual Enable Inputs, SYNC Input, and Manual external frequency synchronization. Moreover, a Reset Input CLKOUT output provides a clock signal that is 90 out of phase with respect to the step-up converter, allowing Power-On Reset Output and Power-Fail Output four-phase operation using two MAX5072 ICs in mas- Low-Cost Solution ter-slave configuration. The MAX5072 includes a power-good output for con- Fully Assembled and Tested verter 1, a reset output, and a manual reset input. In addition, each output, can be shut down individually. Ordering Information The MAX5072 features a power-fail output, which pro- vides a logic-low when the input voltage drops below a PART TEMP RANGE IC PACKAGE preprogrammed threshold. MAX5072EVKIT 0C to +70C 32 TQFN-EP* The MAX5072 is available in a thermally enhanced *EP = Exposed paddle. 32-pin thin QFN package.
