LTC6992 - TimerBlox: Voltage-Controlled Pulse Width Modulator (PWM)

The LTC®6992 is a silicon oscillator with an easy-to-use analog voltage-controlled pulse width modulation (PWM) capability. The LTC6992 is part of the TimerBlox® family of versatile silicon timing devices.

A single resistor, RSET, programs the LTC6992’s internal master oscillator frequency. The output frequency is determined by this master oscillator and an internal frequency divider, NDIV, programmable to eight settings from 1 to 16384.

Features
  • Pulse Width Modulation (PWM) Controlled by Simple 0V to 1V Analog Input

  • Frequency Range: 3.81Hz to 1MHz
  • Configured with 1 to 3 Resistors
  • <1.7% Maximum Frequency Error
  • PWM Duty Cycle Error < 3.7% Maximum
  • Frequency Modulation (VCO) Capability
  • 2.25V to 5.5V Single Supply Operation
  • 115μA Supply Current at 100kHz
  • 500μs Start-Up Time
  • CMOS Output Driver Sources/Sinks 20mA
  • –55°C to 125°C Operating Temperature Range
  • Available in Low Profile (1mm) SOT-23 (ThinSOT™) and 2mm × 3mm DFN
