The MIC2285YML-TR belongs to the family of PMIC - Voltage Regulators - DC DC Switching Regulators. It is a high efficiency 8-Pin TDFN package, offering high-voltage isolation and low power consumption. This device is ideal for applications such as motor and industrial control, medical and gaming equipment, and white goods.

The MIC2285YML-TR is an integrated high-performance, low-noise, pulse-width modulation (PWM) step-down switching regulator. It is designed to provide a regulated output from a variety of input sources. The most common input sources include AC, DC, or battery sources. Its main function is to convert unstable, often noisy, input voltage into a stabilized, low-noise DC voltage. The onboard low-power operation provides a high efficiency of up to 90%.

The MIC2285YML-TR is a step-down switching regulator that produces a regulated output voltage from a variety of input sources. It has an integrated pulse-width modulation (PWM) controller that can control an external MOSFET switch, allowing it to switch at a frequency of up to 1.25MHz. The device also features fixed frequency switching, external synchronization, active current limit, soft-start, and spread spectrum modulation to reduce EMI levels. In addition, the device includes a POWER-OK and INPUT-UVLO comparator, along with an under-voltage lockout (UVLO) and over-temperature protection (OTP) circuit.

In addition to the features mentioned above, the MIC2285YML-TR also features a low shutdown current of less than 1µA, a high operating temperature range of -40°C to 85°C, and an accurate output voltage tolerance of ±2%.

The MIC2285YML-TR is ideal for applications that require high efficiency and low noise, such as motor and industrial control, medical, gaming equipment, and white goods. It is also suitable for powering low-voltage/high current loads such as DC motors, LED lighting, and LCD/plasma displays.

The working principle of the MIC2285YML-TR is quite simple. When a voltage source is applied, the device switches on and begins to regulate the output voltage. The onboard low-power operation ensures the high efficiency of up to 90%. The integrated pulse-width modulation (PWM) controller then controls an external MOSFET switch, which switches at a frequency of up to 1.25MHz. The device also features fixed frequency switching, external synchronization, active current limit, soft-start, and spread spectrum modulation to reduce EMI levels. As the output voltage is changed, the device adjusts its switching frequency accordingly to maintain an optimal output voltage.

The MIC2285YML-TR is an ideal solution for applications that require high efficiency and low noise. Its low-power operation, high efficiency of up to 90%, and its accurate output voltage tolerance of ±2% make it an ideal choice for applications where space, weight, efficiency, and noise reduction are key factors. The device also offers a wide operating temperature range of -40°C to 85°C, making it ideal for applications that require reliable operation in harsh environments.
