Working Principle of TPS62162QDSGTQ1

The TPS62162QDSGTQ1 DC-DC buck switch regulator system works by regulating the output voltage to a precisely regulated level. This is accomplished by using a pair of MOSFETs to alternately pulse the voltage into a filter capacitance. In a normal operation, the duty cycle of the MOSFETs is regulated to accurately split the input voltage into two equal voltage rails, creating a precisely regulated output voltage. The device also features a high voltage input protection which prevents the device from drawing too much current and damaging the power system.

The TPS62162QDSGTQ1 can operate in forced PWM mode for reliable operation, and forced PWM mode can also be disabled for ultra-low noise operation. The device features a built-in soft-start feature which can be used to minimize thermal stress on the MOSFETs, as well as to reduce inrush current. The device also features a built-in skip initialization circuit to minimize power consumption in standby mode. The device also integrates protections such as under-voltage, over-voltage, and over-temperature protection to ensure reliable operation in a range of environmental conditions.
