MIC2196YM-TR

The MIC2196YM-TR is a microcontroller-compatible, high-performance current-mode DC-DC switching controller featuring a wide range of features and options. The MIC2196YM-TR is ideal for a variety of power supply designs, including boost, buck, and flyback topologies. The device also provides automatic burst mode and external loop compensation, an adjustable soft-start, an adjustable current limit, an adjustable slew rate limit, and programmable UVLO and OTP protection.

The MIC2196YM-TR belongs to the PMIC - Voltage Regulators - DC DC Switching Controllers category. It is an integrated circuit with a dedicated purpose to control the output voltage in a switching power supply. It works by using an internal Pulse-Width Modulation (PWM) controller to adjust the switching frequency of an external power switch. It also provides protection features such as Under Voltage Lockout (UVLO) and Over Temperature Protection (OTP).

The MIC2196YM-TR provides adjustable current limits, adjustable soft-start, adjustable Slew Rate Limit, programmable UVLO and OTP protection. The current limit is adjustable from 0.5A to 2.5A and the Slew Rate Limit can be set from 0A/µs to 8A/µs. The adjustable soft-start provides an adjustable voltage ramp of between 0.45V and 4.5V, with a typical ramp time of 1.5ms. The Adjustable Slew Rate Limit helps reduce the inrush current at startup of the switching frequency and ensure stability of the power supply design.

The UVLO feature ensures that the output of the buck converter is shut down when the input voltage falls below a predetermined level, thereby protecting the power switch from operating in the under voltage range, which can cause severe damage to the switch when subjected to high voltage transients. The OTP feature ensures that the output of the buck regulator is shut down if the die temperature exceeds a predetermined level, thus preventing damage to the converter due to over temperature conditions.

The MIC2196YM-TR also features an external loop compensation pin, allowing the user to impleme
