HV3-2405E-5 - World-Wide Single Chip Power Supply


World-WideSingle Chip Power Supply
The HV-2405E is a single chip off line power supply that converts world wide AC line voltages to a regulated DC voltage. The output voltage is adjustable from 5VDC to 24VDC with an output current of up to 50mA. The HV-2405E can operate from input voltages between 15Vrms and 275Vrms as well as input frequencies between 47Hz to 200Hz (see Table 1 in section titled Minimum Input Voltage vs Output Current” for details).
The wide input voltage range makes the HV-2405E an excellent choice for use in equipment which is required to operate from either 240V or 120V. Unlike competitive AC-DC convertors, the HV-2405E can use the same external components for operation from either voltage. This flexibility in input voltage, as well as frequency, enables a single design for a world wide supply.
The HV-2405E has a safety feature that monitors the incoming AC line for large dv/dt (i.e. random noise spikes on AC line, initial power applied at or near peak line voltage). This inhibit function protects the HV-2405E, and subsequent circuitry, by turning off the HV-2405E during large dv/dt transients.This feature is utilized to ensure operation within the SOA (Safe Operating Area) of the HV-2405E.
The HV-2405E can be configured to work directly from an electrical outlet (see Figure 1) or imbedded in a larger system (see Figure 7). Both application circuits have components that will vary based on input voltage, output current and output voltage. It is important to understand these values prior to beginning your design.
