LM5026MTX from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input voltage source to the start-up regulator with operating input range of 13 V to 100 V and transient capability to 105 V. |
| 2 | UVLO | input | Line undervoltage lockout controlled by external voltage divider; enables VCC and REF regulators at 0.4-V threshold and enables SS pin and active mode at 1.25-V threshold. |
| 3 | CS | input | Current sense input for current mode control; exceeding 0.5 V terminates output pulse for cycle-by-cycle current limit; internal switch holds CS low for 100 ns after OUT_A switches high. |
| 4 | RES | input | Restart timer input with external capacitor; 10-µA current source charges capacitor during cycle-by-cycle current limit; 2.5-V threshold triggers soft-start reset and discharge at 1 µA reverting to 50 µA after first pulse. |
| 5 | TIME | input | Gate drive overlap or deadtime control; external RSET resistor to AGND produces in-phase OUT_A and OUT_B pulses with overlap; connection to REF produces out-of-phase pulses with deadtime. |
| 6 | REF | output | 5-V precision reference output with maximum output current of 10 mA; requires local 0.1-µF decoupling capacitor. |
| 7 | VCC | power_in | High voltage start-up regulator output regulated to 7.6 V; supplies power to internal circuitry; auxiliary winding above regulation setpoint disables internal start-up regulator. |
| 8 | OUT_A | output | Main switch PWM gate driver output with 3-A peak sink current capability and compound MOS-Bipolar configuration for superior gate drive characteristics. |
| 9 | OUT_B | output | Active clamp switch gate driver output with 0.5-A peak source and sink current capability; can drive P-Channel or N-Channel clamp switches. |
| 10 | PGND | power_in | Power ground connection; must connect directly to analog ground with short direct connection to AGND to avoid jitter. |
| 11 | AGND | power_in | Analog return ground connection; must connect directly to power ground with short direct connection to PGND to avoid jitter. |
| 12 | SS | input | Soft-start control pin; external capacitor with internal 50-µA current source sets soft-start ramp; current reduced to 1 µA following restart; soft-stop discharge current is 50 µA. |
| 13 | COMP | input | Pulse width modulator input accepting control current from external optocoupler error amplifier; zero input current produces maximum duty cycle while 1 mA reduces duty cycle to zero. |
| 14 | RT | input | Oscillator frequency control normally biased at 2 V; total external resistance connected between RT and AGND sets the internal oscillator frequency. |
| 15 | SYNC | bidirectional | Oscillator synchronization input/output; internal oscillator can synchronize to external clock via pulldown device; multiple LM5026 devices can be synchronized by connecting SYNC pins together. |
| 16 | DCL | input | Maximum duty cycle control; external resistor divider from RT to AGND sets the maximum output duty cycle for OUT_A. |
