TPS63030DSKR Description

The TPS6303x devices are the best way to power a wide range of devices that use alkaline, NiCd, NiMH, single-cell Li-ion, or Li-polymer batteries. These useful tools can run on either two or three alkaline cells or a single cell of Li-ion or Li-polymer.

When you use a single-cell Li-ion or Li-polymer battery with a TPS6303x device, you can get up to 600 mA of output current. This is enough power for your needs. The most energy is used when the battery is discharged to 2.5 V or less.

Buck-boost converters with PWM controllers that have a set frequency and synchronous rectification work well. The converter goes into power-saving mode easily at low load currents, so it stays efficient over a wide range of load currents. By turning off the power-saving mode, the adapter can switch at a set rate.

To make sure they work well, switches have a maximum average current of 1000 mA. Changes in voltage can be made with an external resistor divider or a chip with a set output voltage. Turning off the converter during shutdown keeps the battery from being used up.

Devices with the TPS6303x series can work in a wide range of temperatures, from -40°C to 85°C. The 10-pin V package makes it easy to build with these devices.

TPS6303x devices are efficient and reliable ways to power apps that run on batteries. With their battery compatibility, speed, and temperature range, these gadgets help your electrical systems work as well as they can.

Detailed Description

The device’s high-tech controlling circuit is “average current mode.” This circuit controls inductor average current with a fast current regulator loop and a voltage control loop. The controller has input and output voltage feed forward for efficiency.

The controller monitors input and output voltages to respond quickly to errors. Change the modulator’s duty cycle immediately. This fixes errors quickly and correctly. The FB pin feeds the voltage error amplifier through an adjustable resistive voltage divider. To acquire an accurate voltage reading, FB is directly linked to the set output voltage. Fixed-output versions have a tunable internal resistance divider. The controller generates a consistent, precise output voltage by comparing the feedback voltage to the internal reference voltage.

The controller circuit monitors average and peak input current. It controls peak input current and power. This function guarantees machine safety and stability. Its inbuilt temperature sensor prevents overheating. Extra security.

Four internal N-channel MOSFETs maintain synchronous power conversion in various operating conditions. This configuration is efficient even if input energy and output power vary greatly.

The device features two ground pins—GND and PGND—because high switch currents can change the ground. Power switches are connected to PGND, and all control functions use GND. A good PCB connects both grounds at one spot, usually around the GND pin. When the converter is off, the 4-switch topology always removes the load from the input. Safer and more convenient converter.

TPS63030DSKR Feature Description

Set the EN pin to a high logic level to turn on the gadget. This turns on the device and lets it work the way it was meant to.

Shutdown Mode: The gadget goes into a shutdown mode when the EN pin is set to GND. In this mode, the regulator stops switching, and all of the control circuits inside the regulator are turned off. Also, the load is no longer linked to the input. During shutdown, it’s important to keep in mind that the output voltage could drop below the input voltage.

How to get started: During the start-up part of the converter, steps are taken to make sure it runs smoothly. In particular, the duty cycle and peak current are controlled so that peak currents coming from the input don’t get too high. This safety measure is put in place to keep the startup process stable and under control.

Device Functional Modes

● Buck-Boost Operation

When the input voltage changes, the device instantly switches between step-down and boost operations to keep the output voltage steady. It has one active switch, one reversing switch, one switch that stays on all the time, and one switch that stays off all the time. This setup is very efficient because switching and transmission losses are kept to a minimum. There is no mode in which all four switches are always moving. When the input voltage is close to the output voltage, the device works best.


The Texas Instruments TPS63030DSKR DC to DC converter is a flexible and useful way to change the voltage levels in electronic devices. With the ability to both not invert and to invert, a variable output voltage, and a high efficiency of 96%, it gives you exact control over voltage levels while reducing power loss. The converter is small, comes in a tape-and-reel package, and can work in a wide range of temperatures. These features make it useful for a wide range of uses and ensure reliable and effective power management. Contact ICRFQ to find out more or to place an order.
