The RT6253A operates in automatic PSM that maintains high efficiency during light load operation. The RT6253B operates in Forced PWM that helps meet tight voltage regulation accuracy requirements. ⚫ The RT6253A/B senses both FETs current for a robust over-current protection (OCP). The device features cycle-by-cycle current limit protection to prevent the device from the catastrophic damage in output short circuit, over-current or inductor saturation conditions. A built-in soft-start function prevents inrush current during start-up. The device also includes input under-voltage lockout, output under-voltage protection, and overtemperature protection (OTP) to provide safe and ⚫ ⚫ ⚫ ⚫  RT6253A : Power Saving Mode (PSM)  RT6253B : Forced PWM Mode Fixed Switching Frequency : 580kHz Enable Control and Fixed Soft-Start with typ. 1ms Safe Start-Up from Pre-biased Output Input Under-Voltage Lockout (UVLO) Protection Function  Output Under-Voltage Protection (UVP) with Hiccup Mode  High- / Low-side MOSFET OCP and OTP Function smooth operation in all operating conditions. ⚫ RoHS Compliant and Halogen Free Simplified Application Circuit RT6253A/B VIN VIN RBOOT (Optional) BOOT CBOOT CIN L VOUT SW Enable EN RFB1 GND CFF COUT FB RFB2 Copyright © 2021 Richtek Technology Corporation.
