Product Overview

RAA211630GNP#HA0 is a DC/DC synchronous step-down regulator w/ internal compensation and programmable frequency. It can deliver up to 3A of continuous output current with premium load and line regulation performance. This uses peak-current mode control architecture. Its PWM switching frequency is programmable to provide the best trade-off between transient response and efficiency. It also supports PFM operation and DEM to maximize light-load efficiency, in addition to an external bias LDO input to further reduce power dissipation across the load range. The regulator also has an internal loop compensation circuit to reduce the external component count and BOM cost. This provides useful functions such as internal or programmable soft-start and power good indicator. Application includes industrial power system, distributed power supplies and general-purpose point-of-load, telecommunication base station power supplies, high-voltage single-board systems.
  • Wide input voltage range from 4.5V to 60V (TA = +25°C)
  • Adjustable output voltage from 0.8V to 90% of VIN
  • Default 400KHz switching frequency and programmable switching frequency range from 200KHz to 800KHz
  • ±1% Load regulation accuracy from -40°C to 125°C, ±0.5% Load regulation accuracy at 25°C
  • Quiescent current is 90µA (typ, EN = 2V, VFB = 0.825V, VIN = 24V, EBIAS = 3.3V, No Switching)
  • Internal compensation
  • Internal 0.5ms soft-start, PFM operation and DEM at light load
  • Integrated external bias LDO, power good indicator, thermal shutdown
  • Input voltage UVLO and output voltage undervoltage (short-circuit) protection
  • QFN package, junction temperature range from -40°C to +125°C
