IC for Quasi-resonant Power Supply
MS1003SH / MS1004SH
Product Launch Announcement

This is to inform you that in June 2012 Shindengen Electric Manufacturing Co., Ltd. (main office located in Ohtemachi, Chiyoda ward Tokyo) announces the development and the sales release of our ICs for quasi-resonant power supplies: “MS1003SH and MS1004SH”.



Controllers for quasi-resonant power supplies that support auto-standby

MS1003SH / MS1004SH

PDGeneral Description

@MS1003SH and MS1004SH consume significantly less power in standby mode than conventional ICs. These ICs incorporate various functions that make them more user-friendly and make it easier to design a power supply with fewer external components.
These ICs can also support a broad range of power capacities by changing the main switching elements.


QDFeatures

@ Quasi-resonant design for high efficiency and low noise
@ Soft drive circuit reduces noise
@ Onboard startup circuit requires no startup resistor
@ Auto-standby function improves efficiency under light loads with no additional components
@ Super standby function further improves efficiency under light loads
@ Equipped with automatic trough skip function controls increases in oscillation frequency and improves efficiency under light loads
@@@(MS1003SH: 1 trough skip / MS1004SH: 2 trough skips)
@ Built-in input voltage dependence correction circuit for droops to reduce the number of components required
@ Equipped with soft start function
@ Surface mount package employed for compact dimensions


RDMain Applications

@ DVD / BD recorders & players
@ Sub-power supplies for flat panel, energy efficient TVs
@ Power supplies for digital-STBs
@ Power supplies for document devices, such as LBP
@ Other


SDPackage Dimension@SOP8/7J F UnitFmm

TDBasic configuration
