STEVAL-ILL015V3

STEVAL-ILL015V3 HB LED driver with diagnostic based on the LED2472G Data brief Description The STEVAL-ILL015V3 evaluation board provides a platform to test and evaluate STMicroelectronics’ LED2472G LED driver. The LED2472G device is a 24-bit constantcurrent LED sink driver with output error detection, suitable for applications such as largearea displays and full-color board panels where improvement in RGB LED resolution and reduction of system costs are important. Features • Two LED2472G devices in TQFP48 package connected to 3 x 16 RGB high-brightness LEDs • STM32 microcontroller • Cost-effective internal high-side oscillator • JTAG interface for microcontroller firmware changes/updates • Mini USB connector for connection with a PC GUI • Test points on the board for each important signal aids laboratory evaluation • Buttons and knob to control the board • Error and overtemperature flag for each LED driver • 3 jumpers to simulate the disconnection of 3 LEDs • 3 jumpers to simulate the shorting of 3 LEDs • Highly-efficient ST1S010 DC-DC switching power supply • Input: 7.5 V to 18 V, 0.7 A • RoHS compliant July 2014 DocID026278 Rev 1 For further information contact your local STMicroelectronics sales office. 1/5 www.st.com C13 100nF ADC HOLE hole2 DDD2 ROH1 ROH1 330 R15 2 HOLE hole3 PC13 S1 1 HOLE hole4 C11 100nF R47 100 D17 BridgeLH R17 VarRez 10K 3V3 LEFT DDD3 ROH2 ROH2 C10 100nF R46 100 2 DistanceHole DistanceHole DistanceHole DistanceHole HOLE hole1 S4 JRST RESET/EXIT DDD1 ST ST_LOGO C14 100nF D18 ST:SM6T18AC GM: K375A 1 2 3 CENTER S2 PC14 3V3 C12 100nF R48 100 S3 PC15 C17 100nF 3V3 3V3 JRST JTRST RIGHT C3 100nF C1 4u7(10u) Ceramic (C,D,E) 25V(35V) EN VIN_A C16 100nF PC13 PC14 PC15 EXTCLK 1 2 3 4 5 6 7 8 9 10 11 12 VIN_SW ST1S10 3V3 ST1S10 FB SW 3 7 L1 3u3 Vbat PC13 PC14 PC15 PD0_OSC-IN PD1_OSC-OUT NRST VSSA VDDA PA0-WKUP PA1 PA2 STM32 3V3 VDD_2 VSS_2 PA13 PA12 PA11 PA10 PA9 PA8 PB15 PB14 PB13 PB12 R19 1k2 R18 5k6 MSS7341-332NLBCoilCraft USRX USTX USDIR U4 JTDO_LE JTDI_CLK 6 2 1 JTRST CN5 9 SYNC AGND PGND 5 4 8 3 4 3 1 JTCK 48 47 46 45 44 43 42 41 40 39 38 37 VDD_3 VSS_3 PB9 PB8 BOOT0 PB7 PB6 PB5 PB4 PB3 PA15 PA14 PA3 PA4 PA5-CLK(SPI1) PA6-MISO(SPI1) PA7-MOSI(SPI1) PB0 PB1 PB2 PB10 PB11 VSS_1 VDD_1 DocID026278 Rev 1 3V3 USRX USTX USDIR 36 35 34 33 32 31 30 29 28 27 26 25 OE1B OE2B CLKOUT JTMS USBDP USBDN U3 STM32F103Cx C2 470nF P5 1 2 1 2 3 P4 4V5 USBDN USBDP 3V3 3 2 1 3 2 1 33R 33R R25 Vcc C5 INHIBIT GND Vin U5 D4 100K 4n7 R22 R23 R20 NC Vout D3 VCC LD39015M33R USB_ESD D2 GND D1 U6 Power for Serial Signal for Serial C4 100uF(47uF) size D, 16V Tantal (D) 16V(10V) 4V5 1k5 4 5 6 4 3V3 3V3 4 3 2 1 5 440247-2 GND D+ DVBUS SHLD J1 1 3 5 7 9 11 13 15 17 19 CN1 2 4 6 8 10 12 14 16 18 20 3V3 LD5 Red 2.0V R16 2k2 3V3 GM: MLW20G C8 10nF JTRST JTDI_CLK JTMS JTCK JRTCK 10K JTDO_LE JRST 10K DBGRQ 10K DBGACK Tantal (A) 10uFsize A16V(10V) 3V3 5 C7 1 2/5 2 1 ADC 13 14 JTDO_LE JTDI_CLK 15 SDO 16 SDI 17 OE2R 18 OE2G 19 20 OE1R 21 OE1G 22 23 24 Schematic diagram STEVAL-ILL015V3 Schematic diagram Figure 1.
