TYPICAL APPLICATION PART LIST PARTS DESCRIPTION MANUFACTURER PART NUMBER SPECIFICATIONS SIZE L1, L2 Inductor Sumida CDRH2D14NP-1R5 1.5µH/1.80A/50mΩ 3.0mmx3.0mmx1.55mm C1 Input capacitor Murata GRM21BR60J106KE19L 10µF/6.3V 0805 C2, C3 Intput capacitor Murata GRM185R60J105KE26D 1µF/6.3V 0603 C4, C5 Output capacitor Murata GRM21BR71A106KE51L 10µF/6.3V 0805 C6, C7 Output capacitor Murata GRM185R60J105KE26D 1µF/6.3V 0603 R1, R2, R3, R4 Resistor Various 1%, SMD, 0.1W 0603 E-PAD 1 2 3 4 56 78 9 10 11 12 13 14 15 16 SCLK VINDCD1 DCDPG FB2 VINDCD2 FB1 SDAT GNDLDO Pin Descriptions PIN NUMBER (TQFN) NAME DESCRIPTION 1 VINDCD1 Input voltage for buck converter DCD1 and it also serves as the power supply pin for the whole internal digital/analog circuits. 2 FB1 Feedback pin for DCD1, connect external voltage divider resistors between DCDC1 output, this pin and ground. For fixed output versions, connect this pin directly to the DCD1 output. 3SCLK I2C interface clock pin. 4SDAT I2C interface data pin. 5 VINLDO1 Input voltage for LDO1. 6VOLDO1 Output voltage of LDO1. 7VOLDO2 Output voltage of LDO2. 8 VINLDO2 Input voltage for LDO2. 9 GNDLDO Power ground for LDO1 and LDO2. 10 DCDPG The DCDPG pin is an open-drain output to indicate the state of the DCD1/DCD2 output voltages. When both DCD1 and DCD2 are enabled, the output is released to be pulled high by an external pull-up resistor if both converter voltages are within the power good range. The pin will be pulled low if either DCD is outside their range. When only one DCD is enabled, the state of the enabled DCD’s output will define the state of the DCDPG pin. The DCDPG state can be programmed for a delay of up to 200ms before being released to rise high. The programming range is 1ms~200ms through the I2C interface. |
