The MIC5159-1.8YM6-TR is a linear regulator controller designed to provide precision regulation to a wide variety of microprocessor and logic systems. It is ideal for a variety of applications where tight regulation, ripple rejection, and low power consumption are key performance requirements. Its small package size and low power consumption make it ideal for portable and battery-powered systems, while its wide input voltage range and high switching frequency make it ideal for a variety of style, space constrained systems.
The MIC5159-1.8YM6-TR contains an integrated error amplifier and logic circuitry to sense load contruction, control output, and protect against fault conditions. The logic circuitry provides pulse-skipping and pulse-width modulation (PWM) output modes, enabling the regulator to maintain tight voltage control and provide excellent load transient response. An internal power MOSFET switch is used to provide fast switching and high efficiency operation. The MIC5159-1.8YM6-TR is designed to operate without the need for external compensation components, and can support load currents up to 5A.
The device is rated for operation over an extended range of temperature and in both commercial and industrial environments. The MIC5159-1.8YM6-TR is offered in a standard 5-lead SC70 and SOT-23-5 package. It is suitable for a range of applications, such as DC-DC converters, power management systems, battery management systems, and telecommunications equipment.
The main features of the MIC5159-1.8YM6-TR include:
- Input voltage range of 2.7V to 5.5V
- Integrated logic and error amplifier
- Pulse-skipping and PWM output modes
- Integral power MOSFET switch
- 5A peak and 3A continuous load current capability
- Stable with no external compensation
- Standard 5-lead SC70 and SOT-23-5 packages
- Up to 95% efficiency
The working principle of the MIC5159-1.8YM6-TR is based on the use of pulse-width modulation (PWM) to regulate the output voltage. When the load current or output voltage is out of its predetermined range, the controller will engage the internal power MOSFET switch, producing energy pulses that determine the amount of output voltage. The frequency of the energy pulses is determined by an internal oscillator, and the duty cycle of each pulse is adjusted to maintain the desired output voltage. The device is internally compensated, meaning that no external components are required for proper operation.
The MIC5159-1.8YM6-TR can also be set to a pulse-skipping mode, which provides higher efficiency than PWM mode in some applications. In this mode, the internal power switch is switched on and off to reduce the amount of time the output voltage is kept at its steady-state level. This reduces the amount of energy needed to maintain a specific output voltage, resulting in higher efficiency.
The MIC5159-1.8YM6-TR provides a wide range of protection features to protect against short-circuit and over-voltage conditions. The device will shut off the internal power switch if it detects an over-voltage or under-voltage condition, and will automatically restart after the condition is remedied. In addition, the device includes under-voltage, over-temperature, and over-current protection. The device is also ESD protected for operation in harsh environments.
In summary, the MIC5159-1.8YM6-TR is an advanced linear regulator controller that provides precision regulation, low current consumption, and wide input voltage range. It is suitable for a variety of applications, including DC-DC converters, power management systems, and battery management systems, where exact output voltages and high efficiency are required. The device offers a range of protection features, along with its small package size, making it ideal for portable and battery-powered systems.
