RT7202K Datasheet | Richtek

Description The RT7202K is a simple yet flexible multipurpose of USB PD controller. By programming, it can operate as either a source or a sink. When used as a source, it can be utilized in an off-line AC-DC converter, as it integrates a shunt regulator, constant voltage (CV) and constant current (CC) control loop with a programmable reference voltage to meet the Programmable Power Supply (PPS) specification. When bined with an external buck or buck-boost controller, it can constitute a DC-DC converter, such as a car charger, and also meet the PPS specification. When used as a sink, it is simple, low cost, yet flexible enough to request required power from a source. If using the RT7202KJ/KT/KS for a sink design, it has an I2C interface and two GPIOs for flexible use and can be easily controlled by another MCU acting as the master. The remended junction temperature range is - 40C to 125C, and the ambient temperature range is - 40C to 105C. 2 Ordering Information - Programmed Firmware Code AABBX AA: Application Code BB: Model Code X: Customer Approved Version Code Package Type(1) QW: WQFN-16L 4x4 (W-Type) (RT7202KD/KJ/KT/KS) S: SOP-10 (RT7202KE/KF/KH/KP) Lead Plating System G: Richtek Green Policy pliant(2) RT7202K Version (Refer to Version Table) Note 1. - Marked with (1) indicated: patible with the current requirements of IPC/JEDEC J-STD-020. - Marked with (2) indicated: Richtek products are Richtek Green Policy pliant. 3 Features - Protocol Support - USB PD 2.0 and 3.0 (PPS) - Highly Integrated - Embedded MCU with a Mask-ROM of 24k B, an OTP-ROM of 8k B (RT7202KD/KE/KF) or 16k B (RT7202KH/KJ/KP/KT/KS), and an SRAM of 2k B - Embedded BMC Transceiver - Wide VDD Operation Range: 3V to 22V - Built-In Shunt Regulator for Constant-Voltage and Constant-Current Regulations - Built-In 10-bit Analog-to-Digital Converter (ADC) - Programmable Cable pensation - The BLD Pin for Output Capacitor Quick Discharge (RT7202KD/KJ/KS) - The VDD Pin for Output Capacitor Quick...
