CHL8212-01CRT is a dual synchronous current-mode PWM controller designed for dc to dc applications. It is a cost effective solution for medium power applications such as notebook adapter, main power adapter, desktop power adapter and server power adapter. The CHL8212-01CRT integrates two high performance integrated FET drivers that can support up to 3 Amps of output current and provide output voltages up to 30V. This controller also includes additional features such as a maximum duty cycle protection (MDP), over-voltage protection (OVP) and under-voltage lockout (UVLO).

The CHL8212-01CRT provides a high precision current-mode control loop that enables tight regulation and fast transient response. The current-mode feedback design reduces the negative output impedance, which helps maintain the stability at high output voltage. Additionally, the CHL8212-01CRT includes a dual-channel integrated FET drivers, which combine the advantages of low power loss and fast transient performance.

The CHL8212-01CRT also incorporates an analog remote sensing feature that allows the user to accurately measure the output voltage. This feature enables the user to adjust the output voltage without the need for an adjustment circuit. The controller also features a programmable soft-start, which allows for a smooth start-up transition, reducing the inrush current. The controller also supports light-load efficiency optimization algorithm to reduce the power consumption in low power load conditions.

The CHL8212-01CRT has a wide temperature operating range of -40°C to 85°C, making it suitable for applications in harsh environmental conditions. The device is housed in an 8-pin SOIC package, and is RoHS compliant. The wide range of features and high accuracy make the CHL8212-01CRT an ideal choice for medium power applications.
