Philips Home Theater BD Player - HTS3564 - HTS3578 – Sofware update – Power supply schematic diagram – Using ics - TNY174-180 - SSC9510

Software upgrade
Software upgrade method:
1.Copy the bin file as "HTS3564_XX.bin".
2.Then use the file to burn the upgrade CD-R/CD-RW.
3.Put the CD in the tray ,let the player loading the disc.
4.If the CD is correct ,it will display the Upgrade Menu ,press the PLAY key on the remote control to start upgrade
5.Afer a while, the tray will open automatically ,but must not power off the player.
6.Don't power off ,wait until the player reset automatically ,the whole upgrade process may need 2 minutes .HTS will auto standby after complete upgrade.
if you upgrade with USB device:
1.step1 is same with DISC upgrade;
2.Copy the renamed bin file(upgrade file) to the root menu of USB device.
3.connect the USB device to HTS ,and switch to USB source;
4.The rest is same to step 4,step 5 and step 6 with DISC upgrade.
ICs USED IN POWER SUPPLY
TNY174-180
Description
TinySwitch-LTincorporates a 650 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a designflexible solution with a low system cost and extended power capability.
Applications
# Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
# DVD/PVR and other low power set top decoders
# Supplies for appliances, industrial systems, metering, etc.
Pin Functional Description
DRAIN (D) Pin:
This pin is the power MOSFET drain connection. It provides internal operating current for both startup and steady-state operation.
BYPASS/MULTI-FUNCTION (BP/M) Pin:
This pin has multiple functions:
1. It is the connection point for an external bypass capacitor for the internally generated 5.85 V supply.
2. It is a mode selector for the current limit value, depending on the value of the capacitance added. Use of a 0.1 capacitor results in the standard current limit value. Use of a 1muF capacitor results in the current limit being reduced to that of the next smaller device size. Use of a 10 muF capacitor results in the current limit being increased to that of the next larger device size for TNY175-180.
3. It provides a shutdown function. When the current into the bypass pin exceeds ISD, the device latches off until the BP/M voltage drops below 4.9 V, during a power down. This can be used to provide an output overvoltage function with a Zener connected from the BP/M pin to a bias winding supply.
ENABLE (EN) Pin:
The switching of the power MOSFET is controlled by this pin.
MOSFET switching is terminated when a current greater than a threshold current is drawn from this pin. Switching resumes when the current being pulled from the pin drops to less than a threshold current. A modulation of the threshold current reduces group pulsing. The threshold current is between muAh75A and muAh115 A.
SOURCE (S) Pin:
This pin is internally connected to the output MOSFET source for high voltage power return and control circuit common.
SSC9510 Current Resonant Type Switching Power IC
The SSC9510 series are controller ICs, incorporating a floating drive circuit for half-bridge type resonance. The product achieves high efficiency and low noise power supply systems by the ZVS and ZCS. The product is recommended for high-efficiency small and standardized power supplies because of easy circuit designs with few external components.
Applications
Switching Power Supplies for
Digital Consumer Equipment; LCD-TVs, PDP-TVs, etc.,
OA Equipment; Severs, Multi-Function Printers, etc.,
Industry Machines, Communication Devices
