DESCRIPTION
The NDTD series is a range of low pro?le DC/DC
converters offering dual outputs over a 2:1 input
voltage range. All parts deliver 3W output power
up to 85oC without heatsinking. A ?yback oscilla-
tor design with isolated feedback is used to give

10mm Min. around component
regulation over the full operating range of 25% to
100% of full load. It is strongly recommended that
external capacitors be used on input and output
to guarantee performance over full load and input
voltage range (see application notes for guidance).
1. Please refer to minimum load application note section on page 4.
2. Measured at full load with external input/output capacitors, refer to test circuit.
3. Calculated using MIL-HDBK-217F with nominal input voltage at full load (ground benign) at 25°C.
4. Please refer to re?ected ripple current measurement circuit on page 3.
All speci?cations typical at T A =25°C, nominal input voltage and rated output current unless otherwise speci?ed.
The plastic case is rated to UL94V-0 and encap-
sulant to UL94V-1 and the connection pins are
formed from a tin plated alloy 42 leadframe.
