The synchronous design uses internal N-channel MOSFETs for both the high-side and low-side switches, eliminating the external Schottky diode. The 2.5MHz frequency allows the use of tiny 1.0-2.2uH inductors in 0805 footprint. The DCS-Control (Direct Control with Seamless transition) architecture provides: (1) Fast transient response without external compensation (the output capacitor ESR is part of the control loop); (2) Seamless transition between PWM (continuous conduction) and PFM (discontinuous conduction) modes at light load, maintaining high efficiency down to 1mA; (3) Fixed-frequency operation at medium\/heavy load for predictable EMI. The no-load supply current is 17uA in PFM mode. The output voltage accuracy is +\/-1.5% over temperature. The minimum on-time is 70ns, allowing high step-down ratios (e.g., 17V to 5V at 2.5MHz). The PG (Power Good) output enables power-sequencing of downstream rails. The device is 95% efficient at 12V input, 5V\/1A output. The -RGTR suffix specifies VQFN-16, tape-and-reel. Applications include: 5V USB power from 12V, post-regulation after automotive 12V, and FPGA power from 5V\/12V rails.","pin_description":"
