Description

The NCP1397B is a high performance controller that can be utilized in half bridge resonant topologies such as series resonant, parallel resonant and LLC resonant converters. It integrates 600 V gate drivers, simplifying layout and reducing external component count. With its unique architecture, including a 500 kHz Voltage Controlled Oscillator whose control mode permits flexibility when an ORing function is required, the NCP1397 delivers everything needed to build
a reliable and rugged resonant mode power supply.

resonant controller, is an electronic device or integrated circuit (IC) used in power electronics to control the operation of resonant mode power supplies. Resonant mode power supplies are a type of switching power supply known for their efficiency and reduced electromagnetic interference (EMI) compared to traditional pulse-width modulation (PWM) power supplies.

Features

1. High−Frequency Operation from 50 kHz up to 500 kHz

2. 600 V High−Voltage Floating Driver

3. Adjustable Minimum Switching Frequency with ±3% Accuracy

4. Adjustable Deadtime from 100 ns to 2 μs.

5. Startup Sequence Via an Externally Adjustable Soft−Start

6. Brown−Out Protection for a Simpler PFC Association

25L1605AM2C PDF Datasheet – Flash Memory – MX25L1605AM2C

Posted on by Pinout

Part Number: 25L1605AM2C, MX25L1605AM2C

Function: 16M-BIT [x 1] CMOS SERIAL FLASH

Package: SOP 8 Pin type

Manufacturer: Macronix International

Images:25L1605AM2C pdf memory

Description

The 25L1605AM2C is a CMOS 16,777,216 bit serial Flash memory, which is configured as 2,097,152 x 8 internally. The MX25L1605A features a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). SPI access to the device is enabled by CS# input.

After program/erase command is issued, auto program/erase algorithms which program/ erase and verify the specified page or sector/block locations will be executed.

Program command is executed on page (256 bytes) basis, and erase command is executes on chip or sector(4K-bytes) or block(64K-bytes).

The MX25L1605A is designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transition. During power up the device automatically resets the state machine in the Read mode. In addition, with its control register architecture, alteration of the memory contents only occurs after successful completion of specific command sequences.
