OB3362F pdf datasheet


The OB3362F is a highly integrated and high performance LED driver that optimized for LCD
backlight application. It integrates a boost driver and 4 channels of current balancer that optimized
to drives multi LED arrays, and thus provides a high performance LED backlight solution with minimized BOM count.

The OB3362F contains a PWM boost driver which uses current mode control and fixed frequency
operation. The operation frequency can be programmed by setting external resistor value at RI pin.



1. 10V gate drive, better MOS compatibility

2. High Efficiency and Compact Size

3. 6V to 30V Input Voltage Range

4. 3% Matching Accuracy Between 4 LED Strings Control Current

5. 100KHz~600KHz Operating Frequency

6. Internal/External PWM Dimming

7. Very Low Standby Power

8. Programmable Over Voltage Protection

9. Under Voltage Lockout(UVLO)

LT8900 PDF Datasheet – Low Cost 2.4GHz Radio Transceiver

This post describes for the Transceiver.

The Part Number is LT8900.

The function of this semiconductor is Low Cost 2.4GHz Radio Transceiver.

The manufacturer of this part is ETC.

See the preview image and the PDF file for more information.

LT8900 Radio Transceiver


The LT8900 is a low-cost, fully integrated CMOS RF transceiver, GFSK data modem, and packet framer, optimized for use in the 2.4 GHz ISM band. It contains transmit, receive, RF synthesizer, and digital modem functions, with few external components. The transmitter supports digital power control. The receiver utilizes extensive digital processing for excellent overall performance, even in the presence of interference and transmitter impairments.

On-chip transmit and receive FIFO registers are available to buffer the data transfer with MCU. Over-the-air data rate is always 1 Mbps even when connected to a slow, low-cost MCU. Built-in CRC, FEC, data whitening, and automatic retry/acknowledge are all available to simplify and optimize performance for individual applications. The digital baseband interface can be either 4-wire SPI or 2-wire I2C-bus. Three additional pins are available for optional reset and buffer control.
