Pico Electronics Inc. DC-DC Converters AVR Series

AVR SERIES

Output Voltages -- 100Vdc up to 1000Vdc at 1 Watt

Miniature, Isolated, and Regulated

The Series AVR High Voltage DC-DC Converters is intended for users needing a miniature, isolated, regulated voltage source. These 1 Watt single output units offer high regulation along with low ripple and stability. AVR Units are protected against input Overvoltage, Output Overcurrent and Over Temperature. With no minimum load required, units can be safely operated from No Load to Full Load. Encapsulated in a miniature case and potted, units will operate over a temperature range of -25ºC to +70ºC with no heatsink or power derating.

These units are suitable for applications like electron beam deflection or focussing, photomultiplier tubes, piezo transducers or any other applications requiring regulated, isolated high-voltage sources.

FEATURES:

  • Input/Output Isolation to 1500V
  • Output Regulation
  • Low Ripple
  • 4 standard input voltages: 5, 12, 24, 28 Vdc
  • Input Over Voltage Protection
  • Output Over Current and Short Circuit Protection
  • Remote Shutdown
  • 1 Watt output power at 70ºC ambient with no heat sink
  • Miniature case and low profile (0.500")
  • PC mountable

TO SHUT DOWN THE UNIT, THE VOLTAGE BETWEEN PINS 2 AND 3 MUST BE 0.28 VDC OR LESS. THE UNIT WILL AUTOMATICALLY RESTARY WHEN THE CIRCUIT BETWEEN PINS 2 AND 3 IS OPEN. PLEASE REVIEW THE TYPICAL EXAMPLES OF SHUT DOWN CIRCUITS BELOW.

TYPICAL START UP RESPONSE

Channel 1: 200 Volt/division; 10 ms/division

Unit Tested: 5AVR1000 (5 Vin, 1000 Vout) operated at full load.

TYPICAL TRANSIENT RESPONSE

Channel 1: 5 Volt/division, 200 ms/division

Load Change: 100% to 0% full load
Recovery time within 0.5% Vout: 28.7ms

Unit Tested: 5AVR1000 (5 Vin, 1000 Vout).
