The TPS40130RHBR is a DC-DC switching controller designed to meet the requirements of point-of-load (POL) converters. The device contains high-performance PWM driver, current limit, and integrated MOSFET gate driver circuitry. The TPS40130RHBR is optimized to provide the flexibility required for a wide range of POL converters.

The current mode architecture of the TPS40130RHBR provides superior line and load transient response as well as excellent output voltage ripple characteristics. The wide input voltage range of 4.5V to 28V can support multiple bus topologies. The low quiescent current and small package size of the TPS40130RHBR make it ideal for low-power POL designs.

Applications of the TPS40130RHBR include portable communication equipment, power supplies, industrial power supplies, and airborne electronics. This device is especially suited for distributed power architectures, where multiple output rails are needed from a single Input voltage source.

The TPS40130RHBR features direct external control of the peak output current for improved light-load efficiency. The internal 0.6A peak current limit threshold operates independent of the external peak current setting. The TPS40130RHBR also features two shutdown modes, which can be used to program the power consumption of the power supply in no-load conditions.

The TPS40130RHBR is capable of driving up to 1A of output current up to 28V input, making it suitable for medium-power applications. The internal compensation circuitry provides a simple and efficient compensation solution, while the internal oscillator gate drive circuit eliminates the need for an external bias network. The TPS40130RHBR also features an internal soft-start circuit to minimize output voltage overshoot during startup.

The TPS40130RHBR utilizes a fixed-frequency voltage-mode control to provide reliable operation and excellent transient response. The internal oscillator circuit can operate at frequencies up to 500kHz allowing design flexibility in pursuit of higher power efficiency.

The TPS40130RHBR features comprehensive fault detection and protection features for critical system protection. It also offers a range of cycle-by-cycle current limiting and overvoltage protection options to protect against overload, overtemperature, short circuit, and overvoltage conditions.

The TPS40130RHBR is a high performance DC-DC switching controller designed for use in POL converters. With its wide input voltage range, high peak current output, and compact package size, the TPS40130RHBR is ideal for a wide range of low-power and medium-power applications. Its integrated circuitry allows for a simple external compensation network and provides robust protection features. Its high-performance voltage-mode architecture provides reliable operation and excellent transient response.
