Posted on by pinout

Part Number: LM3502

Function: Step-Up Converter for White LED Applications

Package: 16 Pin WQFN Type

Manufacturer: Texas Instruments

Pinouts:

LM3502 datasheet

 

Description

The LM3502 is a white LED driver for lighting applications. For dual display or large single white LED string backlighting applications, the LM3502 provides a complete solution. The LM3502 contains two internal white LED current bypass FET(Field Effect Transistor) switches that are ideal for controlling dual display applications. The white LED current can be adjusted with a PWM signal directly from a microcontroller without the need of an RC filter network.

Features

• Drive up to 4, 6, 8 or 10 White LEDs for Dual Display Backlighting

• >80% Efficiency

• Output Voltage Options: 16V , 25V , 35V, and 44V

• Input Under-Voltage Protection

• Internal Soft Start Eliminating Inrush Curren

• 1 MHz Constant Switching Frequency

• Wide Input Voltage: 2.5V to 5.5V

• Small External Components

• Low Profile Packages: <1 mm Height

• 10 Bump DSBGA

 

Applications:

1. Dual Display Backlighting in Portable Devices

2. Cellular Phones and PDAs

DAC082S085 Datasheet – 8-Bit, Micro Power D/A Converter

Posted on by pinout

Part Number: DAC082S085

Function: 8-Bit Micro Power DUAL Digital-to-Analog Converter with Rail-to-Rail Output

Package: 10-lead SON and VSSOP Type

Manufacturer: Texas Instruments

Pinouts:

DAC082S085 datasheet

 

Description

The DAC082S085 is a full-featured, general purpose DUAL 8-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to 5.5V supply and consumes 0.6 mW at 3V and 1.6 mW at 5V. The DAC082S085 is packaged in 10-lead SON and VSSOP packages. The 10-lead SON package makes the DAC082S085 the smallest DUAL DAC in its class. The on-chip output amplifier allows rail-to rail output swing and the three wire serial interface operates at clock rates up to 40 MHz over the entire supply voltage range. Competitive devices are limited to 25 MHz clock rates at supply voltages in the 2.7V to 3.6V range. The serial interface is compatible with standard SPI™, QSPI, MICROWIRE and DSP interfaces.

Features

• Ensured Monotonicity
• Low Power Operation
• Rail-to-Rail Voltage Output
• Power-on Reset to 0V
• Simultaneous Output Updating
• Wide power supply range (+2.7V to +5.5V)
• Industry’s Smallest Package
• Power Down Modes
