Application field and working principle of LTC1729CMS8-8.4#TRPBF

The LTC1729CMS8-8.4#TRPBF is a PMIC – battery charger that provides a highly efficient, single-cell Li-ion charger with a limited thermal design power (TDP) of 8.4W and regulated output voltage of 4.18 volts. It is designed to operate within a wide input voltage range of 3.2V to 45V and is able to supply up to 2.5A of continuous output current. This makes the device ideal for a variety of industrial and consumer products.The device includes an integrated power switch and current sense circuit, with comprehensive protection functions to prevent over- and under-voltage, over-charge and over-temperature protection. The device also features a pre-charge stage for improved cell protection during initial charging stages. It also supports fast charge termination and trickle charging for optimal operation.The device includes an internal switching power control circuit which senses the output current from the input and adjusts the switch control accordingly. This allows the current draw from the power source to be almost equal to the actual load. The device also features a PowerSave Mode, which reduces the input current draw and standby losses when there is no load.The integrated current-mode control architecture provides a constant switching frequency of 1.2MHz and a wide range of adjustable switching frequencies. This allows the power supply to operate efficiently at both light and heavy load conditions. The high switching frequency also allows for a small total component count and a very low EMI output.The LTC1729CMS8-8.4#TRPBF is an ideal solution for any application that requires a high efficiency, single-cell Li-ion battery charger. It is well suited for applications in automotive, industrial automation, consumer electronics, medical, telecom, and portable device markets.ConclusionThe LTC1729CMS8-8.4#TRPBF is an ideal PMIC – battery charger for a wide range of applications. It is robust and reliable, featuring a wide input voltage range, high-efficiency operation, operational PowerSave Mode, and comprehensive protection functions. It is also capable of fast charge termination and trickle charging, making it a versatile solution for a wide range of consumer and industrial products.
