LM76003EVM-500K

User's Guide SNVU562 – October 2017 LM7600xEVM User’s Guide The Texas Instruments LM76002EVM-500K and LM76003EVM-500K evaluation modules (EVM) help designers evaluate the operation and performance of the LM7600x wide-input voltage buck regulator. The output voltage for the device offers configurability from 1-V to 95% of VIN, synchronous rectification, PFM, and forced PWM mode and a 300-kHz to 2.2-MHz adjustable frequency range with a 500-kHz default frequency. It also offers external frequency synchronization, power-good (PG) flag, and a precision enable to program undervoltage lockout (UVLO) and internal compensation. Built in protection includes current limit, overvoltage and undervoltage protection, and thermal shutdown. The LM7600x EVM is configured for an output voltage of 3.3 V and a switching frequency of 500 kHz. Refer to the LM7600x data sheet for additional features, detailed description, and available options. The EVM contains one DC-DC converter (See Table 1). Table 1.

Please refer to Figure 1 for a top view of the EVM and relative placement of the different test points and edge connector. Figure 1. Top View of LM7600x EVM 1.1 Input/Output (I/O) Connector Description VIN – Terminal on J1— is the power input terminal for the converter. The terminal edge connector also provides a power (VIN) and ground (GND) connection to allow the user to attach the EVM to a cable harness. VOUT – Terminal on J2— is the regulated output voltage for the converter. The terminal edge connector also provides a power (VOUT) and ground (GND) connection to allow the user to attach the EVM to a cable harness. GND – Terminal on J1 and J2— are the ground reference for the converter. The terminal edge connector also provides a GND connection for attaching the EVM to a cable harness. EN – Testpoint— is used to enable the converter by supplying a voltage greater than 1.2 V (typ) or just to monitor the voltage on this pin whenever a resistor divider is in place (for precision enable applications). The regulator will be enabled when VIN > 3.5 V. This threshold can be calculated by: § RENT · Enable _ Voltage VIH _ EN ˜ ¨ 1 ¸ © RENB ¹ where • VIH_EN is 1.2 V (typ) (1) PG – Testpoint— is used to monitor the power good flag. This flag indicates whether the output voltage has reached its regulation point. This pin is an open-drain output that requires a pullup resistor to the appropriate logic voltage (any voltage less than 20 V). 2 LM7600xEVM User’s Guide SNVU562 – October 2017 Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated Setup www.ti.com PG_PU – Testpoint— is the top connection of an optional 100-kΩ RPGOOD pullup resistor that ties directly to the open-drain PG pin. Supply an appropriate voltage to this test point, or tie it directly to the VOUT test point to observe the PG flag operation. SYNC – Testpoint — is the input terminal for an optional external input clock to the converter as well a mode pin for converter. The external clock frequency must be between 350 kHz and 2.2 MHz, if used. SW – Testpoint— is used to monitor the voltage on the switch pin and the switching frequency of the voltage regulator. Remove this test point before making any electromagnetic interference (EMI) measurements. VIN_EMI – Edge Connector pin #11 and pin#12— is used to supply the input voltage through an on board LC filter (if one is needed for conducted EMI/EMC measurement). The L1 and CBULK component pads are located on the bottom side of the EVM. Please refer to the EVM schematic for initial suggestion of component values. 1.2 Voltage Setup Set the input voltage (VIN) range for the converter between the operating voltage range of 3.5 V to 60 V. If a load is driven, it should be applied to the VOUT terminal and should not exceed the maximum load current of 2.5 A for LM76002 and 3.5 A for LM76003. 1.3 Operation For proper operation of the LM7600x, VIN, GND, and VOUT should be properly configured as stated above. In this configuration, the device starts up when power is applied, and the output voltage of the regulator (VOUT) will come up to the proper value. The default setting for output voltage of the LM7600x is 3.3 V. Other output voltages can be set by replacing the feedback pin resistor dividers RFBT and RFBB; please consult the datasheet for proper selection of these resistor values. The default frequency for the LM7600xEVM is 500 kHz. If other frequencies are desired, within the frequency range of 300 kHz and 2.2 MHz, the RT resistor value can be changed. See the LM76002/03 device data sheet for proper selection of the RT resistor. Change inductor L2 and total output capacitance for proper control loop operation.

The EVM offers resistors, capacitors and test points to configure the output voltage, precision enable pin, set frequency and external clock synchronization. The PWP WQFN-30 package offers an exposed thermal pad which must be soldered to the copper landing on the PCB for optimal thermal performance. The PCB consists of a 4-layer design. There are 2oz copper planes on the top and bottom and 1-oz copper mid-layer planes to dissipate heat with an array of thermal vias under the thermal pad to connect to all four layers. Test points have been provided for ease of use to connect the power supply, required load and to monitor critical signals. The 12-pin edge connector can also be used to facilitate the use of a cable harness if one is required (refer to the Table 2 section for mating connector part number). Figure 4.
