® RT6362 60VIN, 2.5A, Asynchronous Step-Down Converter with Low Quiescent Current General Description Features The RT6362 is a 2.5A, high-efficiency, peak current mode control asynchronous step-down converter. The device operates with input voltages from 4V to 60V. The device can program the output voltage between 0.8V to VIN. The low quiescent current design with the integrated low RDS(ON) of high-side MOSFET achieves high efficiency over the wide load range. The peak current mode control with simple external compensation allows the use of small inductors and results in fast transient response and good loop stability.          The wide switching frequency of 100kHz to 2500kHz allows for efficiency and size optimization when selecting the output filter components. The ultra-low minimum on-time enables constant-frequency operation even at very high step-down ratios. For switching noise sensitive applications, it can be externally synchronized from 300kHz to 2200kHz.      The RT6362 provides complete protection functions such as input under-voltage lockout, output under-voltage protection, output over-voltage protection, over-current protection, and thermal shutdown. Cycle-by-cycle current limit provides protection against shorted outputs, and softstart eliminates input current surge during start-up. The RT6362 is available in WDFN-10SL 3x3, MSOP-10 (Exposed pad) and SOP-8 (Exposed pad) packages.   Wide Input Voltage Range  4.5V to 60V  4V to 60V (Soft-start is finished) Wide Output Voltage Range : 0.8V to VIN 0.8V ±1.5% Reference Accuracy Peak Current Mode Control Integrated 150mΩ Ω High-Side MOSFET Low Quiescent Current : 90μ μA Low Shutdown Current : 1.3μ μA Adjustable Switching : 100kHz to 2.5MHz Synchronizable Switching : 300kHz to 2.2MHz Power Saving Mode (PSM) at Light Load Low Dropout at Light Loads with Integrated Boot Recharge FET Externally Adjustable Soft-Start by Part Number Option Power Good Indication by Part Number Option Enable Control Adjustable UVLO Voltage and Hysteresis Built-In UVLO, UVP, OVP, OCP, OTP Applications   12V, 24V and 48V Power Systems GPS, Entertainment Simplified Application Circuit RT6362GQW RT6362GFP VIN BOOT VIN CBOOT SW CIN D1 RRT RFB2 RT/SYNC CCOMP1 COMP SS/TR CSS GND PAD Copyright © 2020 Richtek Technology Corporation.
