TPSM63603
Mfr.Part #: TPSM63603RDHR
Manufacturer: Texas Instruments
Package/Case: 30-Pin B0QFN (RDH), 4mm × 6mm × 1.8mm
Description: 3V–36V input, 1V–16V output, 3A synchronous buck power module with enhanced EMI control functions.
The TLVM13630 and TPSM63603 integrate the controller, power MOSFETs, shielded inductor and several passive components into an Enhanced HotRod QFN package.
Both devices support:
3V to 36V input
Up to 3A output current
Adjustable 200kHz to 2.2MHz switching frequency
Constant-frequency FPWM operation
External bias for improved efficiency
Negative-output inverting applications
Power-good output
Overcurrent and thermal protection
–40°C to +125°C junction temperature
Low conducted and radiated EMI
The main selection question is whether the application needs only a low-voltage output up to 6V or requires the wider output and EMI-control functions of TPSM63603.

TPSM63603 is especially useful in systems with higher output-voltage rails or defined EMI frequency requirements.
FAQ
What is the main difference between TLVM13630 and TPSM63603?
TLVM13630 supports outputs up to 6V. TPSM63603 supports outputs up to 16V and adds synchronization, adjustable switch-node slew rate and optional spread-spectrum modulation.
Can both devices operate from a 24V supply?
Yes. Both support input voltages from 3V to 36V, making them suitable for regulated 24V buses. Input transients must remain within the device ratings.
Do TLVM13630 and TPSM63603 require an external inductor?
No. Both modules integrate the shielded power inductor, controller and power MOSFETs.
Are the two modules pin-compatible?
They use the same 30-pin, 4mm × 6mm RDH package. TI lists TPSM63603 as a drop-in replacement with upgraded functionality, but the external configuration should still be reviewed.
Which device is better for low-EMI designs?
Both are designed for low EMI. TPSM63603 provides more control through frequency synchronization, adjustable switch-node slew rate and optional spread-spectrum modulation.
Can these modules generate a negative output?
Yes. Both support negative-output operation when configured as an inverting buck-boost converter.
