Buck Regulator EVB User Manual Introduction Introduction The XR77103-MoCA PMIC is designed to power MaxLinear’s MoCA 2.0 MxL370x and MoCA 2.5 MxL371x along with a single port Ethernet PHY such as the GPY241 device. It features three high efficiency synchronous buck regulators with integrated power switches and sequencing engine to provide the 0.9V, 1.8V, and 3.3V rails of the MoCA SoC. The 0.9V core rail can supply the 3A peaks demanded by the SoC and is compatible with the SoC DVS control. The XR77103-MoCA can operate with 5V, 9V, and 12V powered systems with minimal required external components. The XR77103-MoCA is also packaged in a 4x4mm QGN which provides the smallest size solution possible. Quick EVB Set Up and Start Up Factory Settings The evaluation board has been set up with the following factory default configuration for quick set up and operation: ■ ■ VIN = 5.5V to 14V, optimized for a 12V input rail. Maximum IOUT per channel is 2A. ■ ■ Hz Switching frequency. ■ Low power spectral density (PSM) mode operation enabled. Two channels may be paralleled for output currents up to 5A peak and 4A steady state (however additional hardware modification is required for parallel operation). Quick Start Up To quickly see the regulator in operation: 1. Use the factory settings and default configuration. If other settings or components are desired, apply them before the next steps. For more information, see “System Set-Up” on page 5 for more. 2. Connect a turned-off power supply that is within the above VIN specification (from 5.5V to 14V, 12V typical) to VIN+ and VIN- with short and thick leads. Use test pins EXT. VIN (J39) and AGND (J7) to connect and monitor VIN+ and VIN- respectively. See locations in Figure 1 on page 2. 3. Initially set to 0A, connect electronic loads to each desired channel that will be no more than the maximum IOUT (2A) to VOUTx and PGNDx (where x = the channel number) with short and thick leads. Use test pins in Table 1 on page 1 to connect and monitor VOUTx and PGNDx respectively. See locations in Figure 1 on page 2. For all channels with the electronic load connected, ensure that the respective VIN jumper is installed per Table 1 on page 1. February 14, 2022 4. Turn on the 12V power supply and check VOUT. The EVB powers up and regulates the enabled outputs at 0.9V (Ch1), 1.8V (Ch2) and 3.3V (Ch3) (factory default settings). PGOOD is asserted active high once sequencing is done, outputs are in regulation, and reset timer expires. 5. Set or vary the load (do not exceed the maximum IOUT) and check VOUT and other desired performance levels such as regulation and efficiency. For more information about monitoring, see “I/O and Test Points” on page 4 .

For additional information, refer to the XR77103-MoCA data sheet (206DS). Table 4: Factory Settings Jumper Factory Setting Description Jumper 1-2 EN pin is tied to VCC and channels are enabled at power up. Jumper 1-2 PGOOD is pulled up to VCC. No jumper LDO output is not tied to VIN. EN Pin J3 PGOOD Pin J8 5V Operation J11 VIN Connection to Individual Channels J14, J20, J24 Jumpers installed VIN is connected to VIN1, VIN2, and VIN3. No jumper SYNC is not tied to GND on the board. SYNC Pin J15 Jumper J3 Table 5: Jumper J3 Options for the EN Pin Jumper Options Description Jumper 1-2 (default) The EN (enable) pin is tied to VCC and channels are enabled at power up. Jumper 2-3 The EN (enable) pin is tied to GND, permanently disabling the channels. No jumper The jumper is open, allowing EN to be controlled external to the board. Jumper J8 Table 6: Jumper J8 Pull Up Options for the PGOOD Pin Jumper Options Description Jumper 1-2 (default) PGOOD is pulled up to the VCC pin. No jumper PGOOD is not pulled up by this jumper. Jumper J11 For operation from a 5V rail, it is required that the LDO output is connected to VIN, which can be accomplished by populating J11. This enhances the operation of the drivers for VIN < 5V. February 14, 2022 Important: Remove J11 for operation at higher VIN. The board also has Zener diode placeholders which can be installed to protect the IC if higher VIN is accidentally applied. 010-MCUMR00 5 XR77103-MoCA Universal PMIC 3 Output Buck Regulator EVB User Manual Jumper J11 Table 7: Jumper J11 and Operation from a 5V Rail Jumper Options Description Jumper 1-2 Ties the LDO output to VIN which is required for 5V operation. No jumper (default) LDO output is not tied to VIN. Jumpers J14, J20 and J24 Jumper J15 Jumpers J14, J20 and J24 are available to connect or disconnect VIN from VIN1, VIN2, and VIN3 respectively. Factory default is VIN is connected to VIN1, VIN2, and VIN3. Jumper J15 is available to ground SYNC. Factory default is that the SYNC pin is grounded on the board. When not grounded, the SYNC pin may be connected and synchronized to an external clock in applications where EMI control is critical.
