The TPS62003DGS is a non-synchronous boost regulator with integrated FET, power save mode and programmable output voltage, making it a great choice for battery powered applications requiring fast 1.8 V to 5.4 V output voltage conversion. This regulator offers high dropout capability, small size and low quiescent current (17 μA at no load). The high-side N-Channel MOSFET switch allows operation over wide input voltage range of 1.7V to 8V. The low output ripple, low noise, low EMI and fast transient response make the TPS62003DGS an ideal choice for portable devices such as digital still and video cameras, mobile phones, PDAs and GPS devices.

TPS62003DGS application field includes powering core voltage for MCUs, memory and low voltage analog rails, Flash memory card, LCD bias voltage, and White LED backlighting. The regulator also has dedicated solutions suitable for driving 1-1.2V displays from 3V or 2.8V Li-Ion Battery, where a low input and output ripple voltage is necessary to meet EMI standards.

The working principle of the TPS62003DGS is a synchronous rectification based boost regulator, which can handle a wide input voltage range from 1.7V to 8V. A low on-resistance P-Channel MOSFET is connected between the output and input of the device; when the internal PWM signal is high, the switch is on, allowing current flow through the inductor and increasing the stored energy, while the output voltage will increase too. When the PWM signal goes low, the switch is off and the stored energy is released to the output to regulate its voltage. By using a synchronous P-Channel MOSFET, a high efficiency circuit can be implemented.

The TPS62003DGS also features adjustable soft start, which prevents large inrush current on output capacitor during startup, and an adjustable Power Save Mode (PSM) that allows the device to transition to low power mode automatically when no load or light load condition is detected.

The TPS62003DGS is a highly integrated boost regulator, offering high efficiency and low quiescent current with very small form factor. It is an ideal solution for tasks that require a wide input voltage range, high efficiency, fast transient response and low output noise.
