MAX77826 Evaluation Kit
General Description
The MAX77826 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX77826 power-management IC. The MAX77826 includes 1 BUCK regulator, 1 BUCK-BOOST regulator, 15 LDOs (3 NMOS LDOs and 12 PMOS LDOs) and an I2C Interface. The I2C interface supports output-voltage setting , turning on/off of all regulators and reading interrupt/status registers. The MINIQUSB interface board can be used to enable PC communication through the USB interface board. Windows® 2000-, Windows XP®-, Windows Vista®-, and Windows 7-compatible software along with an extender board allows an IBM-compatible PC to use to the USB port to emulate an I2C 2-wire interface. This menu-driven program offers a graphical user interface (GUI) with control buttons.

Procedure
The MAX77826 EV kit is a fully assembled and tested surface-mount board. Follow the steps below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. 1) Visit www.maximintegrated.com/evkitsoftware to download the latest version of the EV kit software, xx.ZIP. Save the EV kit software to a temporary folder and uncompress the ZIP file. 2) Install the EV kit software on your computer by running the INSTALL.EXE program inside the temporary folder. The program files are copied and icons are created in the Windows Start | Programs menu. 3) Carefully connect the MINIQUSB+ command module with the MAX77826 EV kit by aligning the 16-pin connector J1 and 8-pin receptacle J2 of the MAX77826 EV kit with the 16-pin receptacle J3 and 8-pin header J4 of the MINIQUSB+ interface board, respectively. 4) Connect the USB cable from the PC to the MINIQUSB+ command module. 5) Preset the power supply to 3.7V. Turn off the power supply. 6) Connect the positive lead of the 3.7V power supply to the VBATT pad. Connect the negative lead of the 3.7V power supply to the GND pad. 7) Turn on the power supply. 8) Move Jumper JU6 from 2-3 to 1-2 (chip enable). 9) Start the MAX8904 program by opening its icon in the Start | Programs menu. The EV kit software main window appears, as shown in Figure 1. 10) Wait until seeing Command Module Connected, Device Connected as shown in Figure 1. 11) Click Turn on All Regulator button. 12) Verify that all regulators output default voltage.

MAX77826 Evaluation Kit Detailed Description of Software
The MAX77826 EV kit uses the MINIQUSB+ command module for an I2C interface to control the MAX77826 IC. The EV kit software displays six tabs to control and monitor status of the MAX77826 IC, INTERRUPT, STATUS, OPMD, CFG(1), CFG(2), and FREQ/UVLO/DEVICE_ID.
INTERRUPT Tab
The INTERRUPT tab sheet allows user to monitor interrupts (refer to MAX77826 data sheet for details) and mask each interrupt if needed.

Detailed Description of Software BUCK Regulator
The MAX77826 includes a 3A current-mode BUCK regulator. In normal operation, BUCK consumes only 22µA quiescent current. In low power mode, the quiescent current decreases to 8µA with reduced load capability. The summary of features is: ●●
3A (max) output current rating
●●
2.6V to 5.5V input voltage range
●●
Output voltage range from 0.50V to 1.80V in 6.25mV steps
●●
±1% (typ) output voltage DC accuracy
●●
2MHz (typ) switching frequency
●●
Automatic SKIP/PWM or forced PWM modes • 90% peak efficiency
●●
Programmable slew rate for increasing output voltage settings
BUCK BOOST Regulator
The MAX77826 BUCK BOOST regulator utilizes a fourswitch H-bridge configuration to realize BUCK, BUCKBOOST, and BOOST operating modes. In this way, this topology maintains output voltage regulation when the input voltage is greater than, equal to, or less than the output voltage. The MAX77826 BUCK-BOOST is ideal in Li-ion battery powered applications, providing 2.6V to 4.1875V output voltage and up to 2A output current across the input voltage range. High switching frequency and a unique control algorithm allow the smallest solution size, low output noise, and highest efficiency across a wide input voltage and output current range.

LDO Regulator
The MAX77826 provides 15 low-dropout linear regulators, including 3 NMOS LDOs, 6 PMOSLV LDOs, and 6 PMOSLS LDOs. Each of these regulators draws 27µA / 18µA (NMOS / PMOS) of quiescent current in normal operating mode and < 5µA in Low Power mode. PMOSLV LDOs allow input voltages as low as 1.7V for optimized system efficiency. All regulators can be operated in Low Power mode which supports up to 5mA of maximum load current. The summary of features is: ●●
3 NMOS LDOs (VOUT Range: 0.6V to 2.1875V with 12.5mV Step) • 1 x 150mA • 1 x 450mA • 1 x 600mA
●●
6 PMOSLV LDOs (VOUT Range: 0.8V to 3.975V with 25mV Step) • 3 x 150mA • 3 x 300mA
●●
6 PMOSLS LDOs (VOUT Range: 0.8V to 3.975V with 25mV Step) • 3 x 150mA • 3 x 300mA
●●
±1.5% Typical Output Voltage DC Accuracy
●●
70dB PSRR at 1kHz
