Specified for an extended range of -40°C to 105°C (TA).
As of recent data, the TSUM1PFR-LF has "low popularity" but is still available through various distributors.
: It receives analog video signals, performs analog-to-digital conversion, scales the image to the panel's native resolution, and outputs the processed data via LVDS.
An internal micro-controller unit (MCU) manages OSD (On-Screen Display) and system logic. Tsum1pfr-lf Datasheet
Because MSTAR Semiconductor was acquired, finding the authentic, original direct PDF datasheet can be challenging on mainstream manufacturer portals. However, several options exist for engineers looking to finalize their schematics:
: Optimized for panel resolutions up to WXGA+ (1440x900) and SXGA+ (1400x1050) .
Requires 3.3V and 1.8V inputs, often stabilized by ICs like AP1084 or AZ1117. Handling & Implementation Specified for an extended range of -40°C to 105°C (TA)
These receive high-frequency analog signals from standard VGA inputs. They consist of dedicated pins for Red, Green, and Blue analog lines alongside Horizontal Sync (H-Sync) and Vertical Sync (V-Sync) signal pins. 2. LVDS Interface Output Pins

The TSUM1PFR-LF supports panel interface formats. This is the industry standard for driving notebook panels and desktop LCD displays. D. Integrated Microcontroller (MCU) Requires 3
Designed to operate in industrial or commercial environments (often rated up to 105°C). Key Functionalities
| Pin No. | Name | Description | | :--- | :--- | :--- | | 1 | VCC | Supply voltage (12V typical, 20V max) | | 2 | GND | Ground reference | | 3 | FB | Feedback input from output voltage divider | | 4 | COMP | Compensation pin for loop stability | | 5 | CS | Current sense input (external resistor to GND) | | 6 | OUT | Gate drive output for external MOSFET |
: Because the chip features a compact LQFP-64 form factor, the PCB layout must incorporate ample copper pours connected to ground pins to act as a heat sink, ensuring long-term operational stability.
For those requiring the full technical documentation, searching for "TSUM1PFR-LF PDF" or checking electronic component supplier sites like Veswin is the recommended approach to obtain the precise pinout diagram and schematics.
