New from Monolithic Power Systems (MPS) is the MP1542, a current mode, step-up convertor that uses a 2A, 0.18ohm internal switch to provide a highly efficient regulator with a fast response. The MP1542 can operate at 700kHz or 1.3MHz, supporting easy filtering and low noise. An external compensation pin affords the user the flexibility to set loop dynamics, which allows the use of small, low-ESR ceramic output capacitors.
A soft-start facility results in a low inrush current and can be programmed with an external capacitor.
The MP1542 operates from an input voltage as low as 2.5V and can provide a 12V, 500mA output from a 5V supply at greater than 90% efficiency.
Protection features of the MP1542 include undervoltage lockout, current limiting and thermal overload protection.
The MP1542 is available in a low profile, 8-pin MSOP and operates over an ambient temperature range of -40 to +85C.
This device is suitable for applications such as LCDs, portable appliances and digital still and video cameras.
