TM2042系列
Description
TM2042 is an inductorless charge pump DC/DC converters. It produces a fixed
5V output voltage. The device has been designed for low noise and high efficiency
application, the maximum output current is 100mA. The constant frequency 1.8MHz
charge pump keep the chip operation from interfering with hypersensitive IF
frequency channel. Low external parts count (one flying capacitor and two small
bypass capacitors at VIN and VOUT) make the TM2042 ideally suited for small,
battery-powered applications.
High switching frequency enables the use of small ceramic, and reduces both
output and input ripple. The TM2042 have thermal shutdown capability and can
survive a continuous short circuit from VOUT to GND. Built-in soft-start circuitry
prevents excessive inrush current during start-up. A low current shutdown feature
disconnects the load from VIN and reduces quiescent current to less than 1uA.
The TM2042 is available in a 6-pin SOT23 package.
