TC1303B-1P0EMF Application Field and Working Principle

PMIC - Voltage Regulators - Linear + Switching

The TC1303B-1P0EMF is a step-down DC-to-DC power management integrated circuit. This device is designed to provide a high degree of flexibility and performance in voltage regulation, in both linear and switching applications. It operates over an input supply range of 4V to 15V, and provides a fixed output voltage of 0.9V. The TC1303B-1P0EMF is ideal for notebook computers, tablets, and other applications that demand a high level of voltage regulation accuracy. The device provides excellent regulation accuracy with a typical temperature coefficient of 25 ppm/°C (over a -40°C to +125°C temperature range). The device also features fast transient response and high ripple rejection, making it excellent for supplying rails for microcontrollers and DSPs.The TC1303B-1P0EMF is a single-output device, and includes a built-in adjustable voltage reference. This adjustable reference can be used to adjust the output voltage from 0.75V to 1.2V. The reference is also used for enabling low-noise operation, providing stable operation even under changing temperatures or load conditions.The TC1303B-1P0EMF also features a built-in power switch, which can be used to reduce leakage current when the output voltage is not needed, or to significantly reduce power consumption. This power switch can be used in combination with a power-on reset (POR) circuit, allowing the system to gracefully power-up and shut-down. The TC1303B-1P0EMF features a range of protections and features that ensure reliable, safe operation. The device includes under-voltage lockdown (UVLO) protection which prevents it from turning on if the input voltage is too low, over-voltage protection which prevents it from turning on if the input is too high, current sense and soft-start which protect against inrush current, and over-temperature protection (OTP) which protects against damaging high temperatures. The device also includes an internal frequency oscillator that provides low-noise and stable operation. In summary, the TC1303B-1P0EMF is a high-performance, low-power integrated circuit for providing voltage regulation. It offers excellent regulation accuracy, high ripple rejection, fast transient response and low-noise operation, making it the perfect choice for a variety of applications. It also features a wide range of protection and features to ensure safe and reliable operation.
