Specifications of any and all SANYO Semiconductor products described or contained herein stipulate the
performance, characteristics, and functions of the described products in the independent state, and are
not guarantees of the performance, characteristics, and functions of the described products as mounted
in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an
independent device, the customer should always evaluate and test devices mounted in the customer's
products or equipment.
SANYO Semiconductor Co., Ltd. strives to supply high-quality high-reliability products. However, any
and all semiconductor products fail with some probability. It is possible that these probabilistic failures
could give rise to accidents or events that could endanger human lives, that could give rise to smoke or
fire, or that could cause damage to other property. When designing equipment, adopt safety measures
so that these kinds of accidents or events cannot occur. Such measures include but are not limited to
protective circuits and error prevention circuits for safe design, redundant design, and structural design.
In the event that any or all SANYO Semiconductor products (including technical data,services) described
or contained herein are controlled under any of applicable local export control laws and regulations, such
products must not be exported without obtaining the export license from the authorities concerned in
accordance with the above law.
No part of this publication may be reproduced or transmitted in any form or by any means, electronic or
mechanical, including photocopying and recording, or any information storage or retrieval system, or
otherwise, without the prior written permission of SANYO Semiconductor Co., Ltd.
Any and all information described or contained herein are subject to change without notice due to
product/technology improvement, etc. When designing equipment, refer to the "Delivery Specification"
for the SANYO Semiconductor product that you intend to use.
Information (including circuit diagrams and circuit parameters) herein is for example only; it is not
guaranteed for volume production. SANYO Semiconductor believes information herein is accurate and
reliable, but no guarantees are made or implied regarding its use or any infringements of intellectual
property rights or other rights of third parties.
Tr1 :
External switching transistor. We recommend using a device with IC = 2.5A and fT = 30 to
50MHz. Note that if a transistor with fT = 100MHz or higher is used, it may induce oscillation in
the switching waveform. In this case, we recommend adding a base resistor of about 10
, and
adjusting the circuit so that oscillation does not occur.
D1 :
Flywheel diode to take up the energy from the coil. We recommend using a Schottky barrier diode
with a low VF.
L1 :
We recommend using a 200
H coil. In particular, we recommend a coil in the inductance range
180 to 220
H, a DC resistance of under 0.3, and a maximum allowable current of over 0.4A.
Headphone Block
C1 and C2 :
Input capacitors. We recommend a value of 0.1
F.
C3 :
Ripple filter capacitor. We recommend a value of 47
F.
C16 and C17 :
Oscillation prevention capacitors. We recommend using polyester film capacitors with excellent
thermal characteristics. These are used together with R6 and R7.
C18 and C19 :
Output capacitors. We recommend a value of 100
F.
