Key Features
- Dual independent 400mA step-down channels in a single IC, reducing BOM count and board area in multi-rail designs
- 2.25MHz fixed switching frequency minimizes external inductor and capacitor size for ultra-compact power stages
- Automatic PWM/PFM mode switching maximizes efficiency across the full load range from light to heavy loads
- Wide adjustable output range 0.6V to 6V from a 2.5V to 6V input, covering most low-voltage digital and analog rails
Applications
The TPS62400DRCR is designed for portable consumer electronics, wireless modules, and IoT devices that require two independently regulated supply rails from a single lithium-ion or lithium-polymer battery. Its 2.25MHz switching frequency and automatic PFM mode allow designers to achieve high efficiency at both light and heavy loads while minimizing the size of external passive components in space-critical handheld and wearable applications.

Frequently Asked Questions
What is the output current capability of each channel in the TPS62400DRCR?
Each of the two step-down channels in the TPS62400DRCR can deliver up to 400mA of continuous output current, providing sufficient power for digital processors, RF transceivers, and peripheral ICs in battery-operated designs.
What is the switching frequency of the TPS62400DRCR?
The TPS62400DRCR operates at a fixed 2.25MHz switching frequency, which allows the use of very small surface-mount inductors (typically 1µH) and ceramic capacitors, significantly reducing the overall solution footprint on the PCB.
What input voltage range does the TPS62400DRCR support?
The device accepts an input voltage from 2.5V to 6V, making it compatible with single-cell Li-ion/LiPo batteries (2.7V to 4.2V) as well as regulated 5V USB power sources and 3.3V system rails.
Can the output voltage of the TPS62400DRCR be adjusted?
Yes, each output channel is independently adjustable from 0.6V to 6V using an external resistor divider on the feedback pin, giving designers the flexibility to set any standard voltage such as 1.0V, 1.2V, 1.8V, or 3.3V for their specific load requirements.
What package is the TPS62400DRCR available in and is it lead-free?
The TPS62400DRCR comes in a compact 10-pin VSON (S-PDSO-N10) surface-mount package with an exposed thermal pad for improved heat dissipation. It carries a Pb-free (lead-free) designation and is RoHS compliant, meeting current environmental regulations.
