15 Watt DC-DC Converters

a) Adjustment by means of an external resistor R_ext

Auxiliary Functions

Depending upon the value of the required output voltage,

the resistor shall be connected:

Shutdown Function

The outputs of the converters may be enabled or disabled by

means of a logic signal (TTL, CMOS, etc.) applied to the shut-

down pin. If this function is not required, the shut-down pin

should be left open-circuit.

Adjustable Output Voltage

• R input for single-output models and -0503-models

• Trim input for double-output models

b) Adjustment by means of an external voltage V_ext

between Vo– and R pin.

• R input as option R for most double-output models.

The control voltage range is 1.96 to 2.62 V and allows for

adjustment in the range of V_o≈ 80 to 105% of V_{o nom}

As a standard feature, the single- and double-output models

offer adjustable output voltage(s) by using the control input R

or Trim. If the control input is left open-circuit, the output

voltage is set to V_{o nom}. For output voltages V_o> V_{o nom}, the

min

Attempting to adjust the output below this range will cause

the converter to shut down (hiccup mode).

Single-output models with synchronous rectifier (G):

Note: Applying an external control voltage >2.75 V may damage

the converter.

The R input is referenced to the secondary side of the

converter. Adjustment of the output voltage is possible by

means of an external resistor connected between the R pin

and either Vo+ or Vo–.
