Princeton Technology
Description : 5V/3.3V Input PLUS TO MINUS VOLTAGE CONVERTER

DESCRIPTION

PT6901 is an open loop current mode control high brightness LED driver IC. PT6901 can be programmed TO operate in either constant frequency or constant off-time mode. The frequency can be programmable set as 30KHz~300KHz. The PT6901 is ideally suited for buck LED drivers. It exports PWM signal TO control the external MOS. The PT6901 supply VOLTAGE input range is from 8V TO 12V, and the output current can be programmed between a few milliamps and up TO more

than 1.0A. PT6901 can drive a single or multiple series LEDs, and provide reliability constant current output by detecting LED peak current.



FEATURES

Description : D/A CONVERTER for Digital Tuning (12-channel, 8-bit, on-chip OP amp., low-VOLTAGE)

■ DESCRIPTION
The MB88146A is an 8-bit D/A CONVERTER with twelve built-in channels. The 12 analog outputs each have a builtin OP amplifier with large current drive-capability.
The data input/output format is CS (chip select) with serial bus connection available.
A built-in 12-bit I/O expander enables serial ↔ parallel conversion (8 of the 12 bits can also be used for analog output).
This product can be used for microcontroller port expansion, electronic level adjustment, replacement of semi-fixed resistance for tuning, etc.

■ FEATURES
• Ultra low power consumption (1.2 mW/chl: typical)
• Ultra compact package
• Built-in 12-channel R-2R type 8-bit D/A CONVERTER
• Built-in 12-bit I/O expander (8 bits also function as analog output)
• Built-in analog output amplifier (sink current 1.0 mA maximum, source current 1.0 mA maximum)
• Built-in power-on detection circuit (initialized at detection of VccD power-on)
• MCU interface compatible with 3 V TO 5 V systems
• Power divided inTO MCU interface power supply (VccD) and OP amplifier power supply (VccA), D/A CONVERTER power supply (VccD)
• Analog output capability from 0 V TO VccA
• Serial data I/O operates TO maximum of 2.5 MHz (in cascade connection, up TO 2.5 MHz when VccD = 5 V, up TO 1.5 MHz when VccD = 3 V)
• CMOS process
