The power architecture of the TLV620612TDSGRQ1 is designed to provide a high-frequency, high-efficiency, isolated, dual-output voltage power conversion solution. The device has a power component area that is designed for a single-phase bridge rectifier with an integrated clamp diode, linear regulator or dual-lane buck converter. This allows the device to provide both complex and simple solutions across multiple applications with different input-output voltage requirements. The power component architecture also provides a variety of isolation solutions for PoE systems. The device also features a fast transient response, operating in PWM or Pulse Frequency Modulation (PFM) modes.

Features

The TLV620612TDSGRQ1 features various internal components, such as an adjustable low-side switch, a wide-input voltage range (2.5V to 6.5V), an integrated PMBus interface, an enable pin that can operate in active-high or active-low modes, and an integrated enable pin. It also includes a high-current MOSFET driver, which allows for faster switching times, improved frequency response, and higher efficiency. The device has an operating ambient temperature range of -40°C to +105°C. It also offers a wide range of protections, including over-voltage protection, under-voltage protection, over-temperature protection, and over-current protection.

Working Principle

The working principle of the TLV620612TDSGRQ1 is based on a switching topology that combines high-frequency operation with high efficiency. The device uses a single-phase bridge rectifier to convert alternating current (AC) input to direct current (DC) output. The DC output is then transferred through two independent power MOSFETs to provide two adjustable output voltage rails. The output voltage is determined by the integrated linear regulator or dual-lane buck converter. The device also includes an enable pin to control on/off sequences and other features. The device has a user-selectable switching frequency range of up to 1.2MHz. The device can operate in either Pulse-Frequency Modulation (PFM) or Pulse-Width Modulation (PWM) mode. The device also has a dual-stage protection architecture that provides under-voltage, over-voltage, over-temperature, and over-current protections.
