CD4511BPWR datasheet

 

Description

CD4511B types are BCD-to-7-segment latch decoder drivers constructed with CMOS logic and n-p-n bipolar transistor output devices on a single monolithic structure. These devices combine the low quiescent power dissipation and high noise immunity features of RCA CMOS with n-p-n bipolar output transistors capable of sourcing up to 25mA. This capability allows the CD4511B types to drive LED’s and other displays directly.

Features

1. High-output-sourcing capability – up to 25mA
2. Input latches for BCD Code storage
3. Lamp Test and Blanking capablility

Part Number: LM3503

Function: Dual-Display Constant Current LED Driver with Analog Brightness Control

Package: MicroSMD 10 Pin, SQA16 Pin Type

Manufacturer: Texas Instruments

Pinouts:

LM3503 datasheet

 

Description

The LM3503 is a white LED driver for lighting applications. For dual display backlighting applications, the LM3503 provides a complete solution. The LM3503 contains two internal white LEDcurrent bypass FET (Field Effect Transistor) switches. The white LED current can be adjusted with a DC voltage from a digital to analog converter or RC filtered PWM (pulse-width-modulated) signal at the Cntrl pin.

Features

• Drives up to 4, 6, 8 or 10 White LEDs for Dual Display Backlighting
• >80% Peak Efficiency
• Output Voltage Protection Options: 16V, 25V,35V & 44V
• Input Under-Voltage Protection
• Internal Soft Start Eliminates Inrush Current
• 1 MHz Constant Switching Frequency
• Analog Brightness Control
• Wide Input Voltage Range: 2.5V to 5.5V
• Low Profile Packages: <1 mm Height
– 10 Bump DSBGA
– 16 Pin WQFN
