Reliability that you can count on
We design this circuit to survive the toughest torture environment including: 1) repeatedly over-night burn-in test w/ minimal cooling, 2) over input voltage test of up to 15V, 3) over-driven output current test of up to 4A, and 4) high temperature duration test.
Our experienced electronic engineers ensure all components are working at its maximum efficiency and highest stability with the optimally planned and implemented circuit pcb layout. All chosen electrical components in this circuit design have good amount of headroom to ensure high stability in long term usage.
Inside the C3300 ST
This highly efficient synchronous buck current regulated circuit controls the precious amount of current that goes through the LED at all output levels. This results in constant brightness output regardless of LED variation, battery voltage, and temperature change. The Low EMI management and quick soft-start design provide clean electricity for the circuit and LED to enhance their service life.
Our synchronous buck converter is more technologically advanced and compact than regular buck converter. It also allows more board space for our exceptionally low DCR mosfets, rugged & shielded power inductor, and low ESR tantalum capacitors. This together leads to very high efficiency and lower required input voltage to current regulate.
The microprocessor is programmed to provide handy and easy-to-use interface for the users. When the flashlight is turned off, it shuts off all unnecessary components and waits to respond to user command at very low standby current (uA).
Excellent runtime & efficiency
TX25C2 runs for 90+ hours on its lowest brightness level. The current regulated circuit design allows constant output throughout its runtime for all output levels without LED flicking.
At its highest brightness output, TX25C2 current regulates for 1 hour with two CR123A and 1.6 hour with EAGTAC 3400mAh batteries. Double the runtime with body extension tube.
Not only we care about the LED runtime, we also care about the runtime when the LED is turned off. The standby power consumption is only measured in merely uA level, which translates to years of standby time period, just like your TV remote control.
