Frequently Asked Questions
What input voltage range does TPSM13604HNDWR support and which industrial bus standards does that cover?
TPSM13604HNDWR accepts 5 V to 36 V input, covering the standard 24 V industrial bus, 12 V automotive rails, and 5 V logic rails. This wide range means a single design handles multiple supply scenarios without redesign, and the 36 V maximum provides headroom for transients on 24 V industrial power buses.
How much output current can TPSM13604HNDWR deliver and what load types is it optimized for?
TPSM13604HNDWR delivers up to 4 A continuous output current, making it suitable for processors, FPGAs, and DSPs that require between 1 A and 4 A at 1.8 V, 3.3 V, or 5 V. Its constant-on-time control handles step-load transients efficiently, maintaining output voltage within tight regulation bands even when load current changes by 2 A or more in microseconds.
What advantages does the integrated-inductor module format of TPSM13604HNDWR offer over a discrete buck converter?
The 7-pin module integrates the power inductor, reducing external component count by at least 1 large magnetics component and shrinking total solution area compared to a discrete buck converter with separate controller, FETs, and inductor. Engineers save PCB routing complexity, eliminate magnetics selection time, and benefit from pre-characterized EMI performance validated at 4 A output.
How does constant-on-time control in TPSM13604HNDWR simplify compensation compared to voltage-mode PWM regulators?
Constant-on-time control in TPSM13604HNDWR requires no external compensation network because the control loop is inherently stable with output capacitors as low as 22 µF. Traditional voltage-mode PWM designs need a type-III compensator with 3 to 5 passive components, while TPSM13604HNDWR's COT architecture achieves sub-100 µs transient recovery with minimal external components.
