The TPS60132PWPG4 is a monolithic Buck switching regulator which is designed for space-constrained, power-limited applications. It is provided in a wide supply range of 3V to 5.5V and an output voltage range of 0.9V to VIN, offering maximum efficiency with 1.2A of current. The integrated chip is optimized with Efficient Low-Voltage Conversion and has a shutdown mode, with excellent efficiency performance.

The output voltage is adjustable via the external resistor divider, and it is able to maintain accurate output voltage under dynamic load conditions with the use of its internal loop compensation circuitry. The chip also features a soft-start circuit which allows up to 2V of output overshoot before it goes back to its nominal voltage. The TPS60132PWPG4 is protected by undervoltage lockout (UVLO) and short-circuit protection.

Applications of this product include portable or battery powered products such as smartphones, digital cameras, personal navigation devices, portable media players, and other consumer electronics. This product is well suited to situations where energy saving and cost efficiency are essential.

The TPS60132PWPG4 switching regulator works by using an internal high-side switch connected with an inductor to transfer energy from the input to the output. The switch receives a control signal from the regulator as it alternately closes and opens, and thus creates a frequency of pulses. As the inductor stores energy (magnetic field) during the on-time, the energy in the magnetic field is released and creates a voltage across the output when the switch turns off, producing a DC output voltage.

The output voltage is regulated by the Pulse width Modulation (PWM) control, together with the feedback divider network, which sense the output voltage at the feedback pin and adjusts the duty cycle so as to maintain the output voltage. The current limiter is set to the desired level, and when the output current nears the limit (over current condition), the voltage regulator will reduce the duty cycle and thus the output current will be limited.

In summary, the TPS60132PWPG4 is a monolithic Buck switching regulator which is ideal for space-constrained and power-limited applications. It has an adjustable output voltage, a soft-start circuit, and is protected by undervoltage lockout and short-circuit protection. The main applications are portable or battery powered products such as smartphones, digital cameras, personal navigation devices and portable media players. The device is able to maintain accurate output voltage under dynamic load conditions and is designed to provide maximum efficiency at a low input voltage level. The TPS60132PWPG4 switching regulator works by using an internal high-side switch connected with an inductor to transfer energy from the input to the output, and PWM control to regulate the output voltage.
