Features and Benefits of ADP1853-EVALZ
Product Detailed Description for ADP1853-EVALZ

The ADP1853 is a wide range input, dc-to-dc, synchronousbuck controller capable of running from commonly used 3.3 Vto 12 V (up to 20 V) voltage inputs. The device nominallyoperates in current mode with valley current sensing providingthe fastest step response for digital loads. It can also beconfigured as a voltage mode controller with low noise andcrosstalk for sensitive loads.

The ADP1853 can be used as a master synchronization clockfor the power system and for convenient synchronizationbetween controllers. The CLKOUT signal can synchronizeother devices in the ADP185x family such that slave devicesare phase-shifted from the master to reduce the input ripplecurrent, improve EMI, and reduce the size of the input bulkcapacitance. The ADP1853 can also be configured as a slavedevice for current sharing. Additionally, the ADP1853 includesaccurate tracking, precision enable, and power good functionsfor sequencing. The ADP1853 provides a high speed, high peakcurrent gate driving capability to enable energy efficient powerconversion. The device can be configured to operate in powersaving mode by skipping pulses, reducing switching losses andimproving efficiency at light load and standby conditions.

The accurate current limit allows design within a narrowerrange of tolerances and can reduce overall converter size andcost. The ADP1853 can regulate down to 0.6 V output using ahigh accuracy reference with ±1% tolerance over thetemperature range from −40°C to 125°C.

With a wide range input voltage, the ADP1853 is designed toprovide the designer with maximum flexibility for use in avariety of system configurations; loop compensation, soft start,frequency setting, power saving mode, current limit, andcurrent sense gain can all be programmed using externalcomponents. In addition, the external RAMP resistor allowschoosing optimal slope and VIN feedforward in both currentand voltage mode for excellent line rejection. The linearregulator and the boot strap diode for the high-side driver areinternal.

Protection features include undervoltage lock out, overvoltage,overcurrent/short circuit, and overtemperature.

Applications
  • Intermediate bus and POL systems requiring sequencing and tracking, including
    • Telecom base station and networking
    • Industrial and Instrumentation
    • Medical and healthcare
