LC4136C-X2T Visão geral
An LED driver is a power-management or interface IC that regulates current or voltage delivered to one or more LEDs. In display equipment, the driver establishes the electrical operating point of backlight LEDs, helping maintain illumination while protecting the light source from excessive current. The LC4136C-X2T is consequently positioned for circuits where an LED load is controlled from an electronic system rather than directly from a supply rail.
The available evidence does not establish whether this part uses constant-current or constant-voltage regulation, how many LED channels it provides, or whether it includes PWM dimming. It also does not confirm a manufacturer datasheet URL. Those omissions prevent a safe characterization of output-current tolerance, switching frequency, efficiency, dimming ratio, thermal resistance, or maximum LED-string voltage. Engineers should obtain the official onsemi technical documentation before selecting it for a new design.
Typical use cases suggested by the verified LED-driver classification include LCD backlight control, panel illumination, indicator lighting, and compact display modules. These are application categories rather than confirmed manufacturer reference designs. Actual suitability depends on the unavailable voltage range, current capability, channel count, pinout, and package data, as well as the LED string topology used in the target board.
Before designing around LC4136C-X2T, verify the manufacturer datasheet, compare every electrical limit against the intended LED string, and confirm that the PCB land pattern matches the required package. Do not substitute a similarly named LC4136 variant without checking pin functions and ratings. The verified LCSC listing reports a price from $0.4707, while other distributor records report $1.16 and $1.33, showing meaningful source and quantity variation.
This page consolidates the supplied distributor identity, pricing, stock, and cross-reference evidence while separating verified facts from missing technical information. It is intended to support initial sourcing and comparison, not to substitute for the complete manufacturer datasheet, PCB footprint, or application validation.

Aplicações típicas
LC4136C-X2T é adequado para 6 aplicaçãos: LCD Backlight Control, Display Panel Illumination, LED Indicator Lighting, Compact Embedded Display Module, Industrial Panel Interface, Battery-Powered Display.
LCD Backlight Control
LC4136C-X2T is identified in the supplied records as an LED driver, making LCD backlight regulation the most relevant category-level application to investigate. A final design requires the official datasheet to confirm LED-string voltage, regulated output current, channel count, dimming method, and package pinout. Engineers should compare those limits with the panel specification and worst-case supply condition. The verified LCSC starting price of $0.4707 is attractive for initial sourcing, but it does not establish electrical suitability or long-term availability.
Display Panel Illumination
The LC4136C-X2T can be evaluated for display-panel illumination when the target LEDs use a topology supported by its unverified electrical ratings. The design process should begin with the LED forward voltage, allowable current, string count, and dimming connector definition. Because the supplied material does not disclose regulation type, output current, or package pins, it cannot confirm direct applicability. Prototype only after checking the official onsemi documentation and comparing worst-case tolerances against the display module requirements.
LED Indicator Lighting
As an LED driver IC, LC4136C-X2T may fit an indicator-light circuit if its input range, current capability, and switching method accommodate the selected LED. Indicator applications often emphasize stable luminous output and simple control rather than high channel count, but those benefits cannot be assumed without specifications. Confirm whether the device regulates current directly and whether its package supports the available PCB footprint. The verified distributor observations show several sourcing channels, including an in-stock LCSC listing, as of 2026-10-23.
Compact Embedded Display Module
LC4136C-X2T may be considered for compact embedded displays where an onboard controller requires a dedicated LED-driver function. The decision depends on package area, pin count, thermal requirements, and whether the display uses a simple two-wire dimming interface or a more complex control scheme. None of those details is present in the verified excerpts, so engineers must not infer compatibility from the onsemi name or LED-driver label alone. Validate with the official family datasheet and inspect the target module schematic before layout changes.
Industrial Panel Interface
The LC4136C-X2T can be assessed for industrial panel illumination where stable LED drive and controlled dimming may improve usability in variable ambient light. An industrial design should verify temperature grade, transient tolerance, current regulation, and protection behavior, but those parameters are unavailable in the supplied sources. Treat the reported $0.4707 LCSC price as a sourcing fact rather than proof of production suitability. Qualification should include thermal testing, startup observation, dimming behavior, and worst-case load testing after the datasheet comparison is complete.
Battery-Powered Display
A battery-powered display may benefit from an LED driver that controls current efficiently, but the supplied LC4136C-X2T data does not disclose efficiency, quiescent current, shutdown behavior, or input-voltage range. These omissions prevent a sound battery-life estimate or regulator-headroom calculation. Engineers should compare the official datasheet limits with the battery's loaded voltage and the LED string's forward-voltage range. They should also confirm whether the package and switching arrangement suit the board's thermal and electromagnetic constraints before selecting the MPN.

Notas de projeto
Do not approve a board change around LC4136C-X2T until the official package drawing and pin table are available. The supplied evidence confirms an LED-driver identity but omits package type, pin count, pin names, and exposed-pad details. Check input power, ground, LED outputs, dimming, fault sensing, and any exposed thermal connection against the actual footprint. A similarly named LC4136 variant must not be assumed to be pin-compatible.
Size the LED load only after confirming the LC4136C-X2T's voltage and current ratings from the manufacturer datasheet. Compare the minimum input voltage, maximum LED forward-voltage stack, regulated current tolerance, startup current, and dimming state against the worst-case supply and LED conditions. The verified snippets provide none of those ratings, so no capacitor, resistor, or efficiency calculation is included here. Preserve the manufacturer-recommended compensation and decoupling network once documented.
Calculate LED-driver and package temperature using the actual LED current, LED forward voltage, driver efficiency, and ambient temperature after those values are verified. Estimated: P_loss = P_in - P_LED, using P_in = V_in x I_in and P_LED = sum(V_F x I_F) across the LED string. Compare junction temperature and copper-area assumptions with the official package thermal data. Do not infer thermal performance from the unknown package or from the distributor price listing.
Place the IC, LED-output path, input decoupling, and any current-sense or feedback components according to the official application circuit. Keep high-current LED loops compact to reduce radiated and conducted emissions, route sensitive dimming or feedback traces away from switching nodes, and provide adequate ground-plane continuity. The exact topology and pin functions are unavailable in the supplied data, so these are general layout controls rather than a substitute for the manufacturer reference layout.
Informações de conformidade
The supplied distributor snippets do not provide verified environmental or material-compliance declarations for LC4136C-X2T.
