LT8304 LT8304-1 Datasheet and Product Info | Analog Devices
Other parts to consider are the LTC3750 and LTC3751.
Thanks！If using LT8304-1,please help to give me a reference circiut to get -500V and 1mA output.
LT8304 is flexible with transformers with one or multiple secondaries, however, the transformer itself does need to meet the minimum inductance, saturing current requirement indicated by datasheet. Please go over the datasheet transfomrer definition…
Page 28 of the LT8304 datasheet shows a 4-100VDC in and 140VDC out boost converter as a typical application (8304 TA11b).
My question is whether there is an application note or some other source of information on how those component values were determined…
1. if I cust down out power level (Iout=0.9A), turn ratio:3:2, just looks like the datasheet recomand, but input voltage range still( 16~40V), the zenner D1 is 18V, if LT8302 work ?
》》18V D1 is a little low, but higher D1 will EOS LT8302, anyway…
See LT8304-1 datasheet, page 24, for a verified 4-18Vin to 400Vout circuit. Rfb resistor could be increased proportionally to generate 450Vout.
Please check out the front page schematic in the below design note:
Choose the resistor values for the output voltage according to:
R2 = R4 • (Vout / 1.6V - 1)…
I had test finish, here I have two questions , please help me.
1. the load from 0% to 100%load(0~1.25A) as 1A/us rating clamp up , here appear so big sound, why ?
2. the ZENER Z1 why choose CMZ5947B（Vz=82V）, I try to change to CMZ5944B …
Transformer datasheet is as follows.
Below is the contact info to obtain transformer sample.

I'm designing signal amplifier using ADHV4702 to amplify signal amplitude up to 80V.
So I'm thinking to make 12VDC VIN to +-50VDC VOUT flyback converter using LT8304 or LT8304-1 for ADHV4702's supply.
Could you recommend proper…
