MIC2193YM-TR Application Field and Working Principle

PMIC (Power Management Integrated Circuit) is a type of integrated circuit that helps to maintain and control the power flow between the power source and the other components of the system. Voltage Regulators, DC-DC Switching Controllers and other peripherals are often part of PMICs. The MIC2193YM-TR is a low-cost side controlled DC-DC converter controllers from Micrel Semiconductor that is specifically designed for applications that require low output current and low input voltage. This DC-DC converter controller can achieve high efficiency in applications such as powering up LCD panels, Ethernet PHYs, and other digital devices. The MIC2193YM-TR can be used as a low-cost alternative to the more expensive ASIC based solutions. The MIC2193YM-TR is specially designed to operate up to 30V input voltages. It provides a wide operating temperature range of -40°C to +85°C and a variety of package sizes and pin out options. The MIC2193YM-TR is designed to provide a high efficiency, low noise, and high reliability DC-DC switching controller solution from a handful of external components. The MIC2193YM-TR features a fixed frequency, side-controlled PFM/PWM (pulse frequency modulation/pulse width modulation) switch that can be enabled/disabled to suit the application. The pulse frequency is typically adjusted to 10KHz in order to reduce the ripple current and switching losses. This high efficiency DC-DC convertor system requires no external compensation network, making it idea for low-cost and low-power applications.The MIC2193YM-TR is designed to easily integrate into existing systems. It provides programmable soft-start and accurate power supply sequencing, as well as a power good output. It also offers low current consumption and low operating temperature, making it suitable for most general-purpose applications. The MIC2193YM-TR also features adjustable current limit for protection during over-current situations. In summary, The MIC2193YM-TR is an ideal DC-DC switching controller for low cost and low power applications. It features side controlled PFM/PWM architecture, low current consumption, accurate power supply sequencing, adjustable current limit, and high efficiency. The MIC2193YM-TR is a great solution for portable and battery powered applications, as well as applications that require low ripple, low noise, and high reliability.
