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

Pin No.
Pin
Function
17
CT
Connection for the oscillator circuit's external capacitor. Connect that capacitor between this pin and ground. When CT is
130pF, fOSC will be 330kHz. If an external clock is applied to this pin, the PWM control functions will operate at that clock
frequency. If an external clock is provided, that signal must be a square wave with a low level of 0V and a high level
between 3.3 and 5.0V. The square wave generator must have a fanout drive capacity of at least 1mA.and UV_DELAY
function doesn't operate when this pin is grounded.
18
PGOOD2
Channel 2 power good pin.
19
SS2
Channel 2 soft start function capacitor connection.
20
TD2
Channel 2 startup delay connection.
21
ILIM2
Channel 2 overcurrent detection trip point setting.
22
RSENS1
Channel 2 overcurrent detection comparator input.
23
FB2
Channel 2 feedback input.
24
COMP2
Channel 2 phase compensation.
25
SGND
IC system ground.
The reference voltage is generated referenced to this pin. The system ground must be connected to this pin.
26
CBOOT2
Channel 2 bootstrap capacitor connection.
27
SW2
This pin is connected to the channel 2 switching node.
28
HDRV2
Channel 2 external high side MOSFET gate drive.
29
LDRV2
Channel 2 external low side MOSFET gate drive.
30
PGND
Power system ground. This pin is used as the current return path for the LDRV pin.
