- Ultra-wide 1.1 V to 20 V input range enables operation from single-cell batteries up to automotive 12 V rails
- Pulse frequency modulation control improves light-load efficiency compared to fixed-frequency PWM controllers
- Up to 1.2 A output current supports LCD bias supplies, piezoelectric drivers, and small motor drives
- 8-pin SOIC package simplifies drop-in replacement on standard boost regulator footprints
Applications
The TL496CDR is optimized for battery-powered equipment requiring a stable 9 V bias rail stepped up from low-voltage cells, such as portable test instruments, handheld medical devices, and remote industrial sensors. Its pulse-frequency modulation scheme maintains high efficiency at light loads common in battery-backed standby circuits, extending operating time between charges. The simple fixed-output topology and SOIC-8 packaging make it well-suited for legacy system repairs and cost-sensitive consumer electronics designs.

Frequently Asked Questions
How low can the input voltage be for TL496CDR to still produce a regulated 9 V output?
The TL496CDR operates with input voltages as low as 1.1 V, which corresponds to a deeply discharged single lithium cell or two series AAA alkaline batteries near end-of-life. This allows the device to continue supplying a regulated 9 V output even as the source battery discharges below 1.5 V, maximizing usable battery capacity in portable instruments.
What control method does TL496CDR use and how does pulse frequency modulation improve battery-powered system efficiency?
The TL496CDR uses pulse frequency modulation (PFM) voltage-mode control. Unlike fixed-frequency PWM, PFM reduces switching frequency at light loads, cutting gate drive and core switching losses proportionally. In a 9 V LCD bias supply drawing 10 mA in standby, PFM can improve efficiency by 10% to 20% compared to fixed-frequency alternatives, directly extending battery runtime in portable devices.
What is the maximum output current TL496CDR can supply, and what types of loads does this cover?
The TL496CDR delivers up to 1.2 A of output current at 9 V, totaling approximately 10.8 W of output power. This is sufficient to drive LCD segment displays, bias operational amplifier circuits requiring a ±9 V split rail from the boosted output, or supply power to small piezoelectric transducers and low-power solenoid drivers in industrial field instruments.
In which scenarios would TL496CDR be a simpler choice than an adjustable boost controller for a 9 V rail?
When the target output is always 9 V and BOM simplicity matters, the TL496CDR eliminates the two external resistors needed by adjustable controllers for output voltage setting. This reduces the risk of resistor tolerance errors causing out-of-regulation voltages, makes layout simpler with fewer sensitive feedback nodes, and lowers total component cost by 2 to 3 parts in high-volume production runs.
