MCH SERIES
1.5 WATT
DC/DC CONVERTERS
Notes:
1. Specified at 50% load.
2. Lin = 2 µH.
3. Maximum duration of short circuit: 25°C-– 90 seconds, 125°C – 30 seconds.
4. Load fault is a short circuit (<50 mohms). Recovery is into resistive full load.
5. Transition
≥ 10 µs. Recovery = time to settle to within 1% of Vout final value.
6. Max. spec indicates 80% of the converter’s total power, available from either
output.
7. Specification applies to both + and – Vout.
8. Although no minimum load is required, at no load the output voltage may
increase up to 15%.
