無(wú)錫禾芯微低功耗降壓DC-DC HX4004A:
The HX4004A is a low noise switched capacitor
voltage doubler. It produces a regulated output
voltage from a 2.7V to 4.5V input. Low external
parts count (one flying capacitor and two small
bypass capacitors at VIN and VOUT) make the
HX4004A ideally suited for small,
battery-powered applications.
The HX4004A have thermal shutdown
capability and can survive a continuous short
circuit from VOUT to GND. A low current
shutdown feature disconnects the load from VIN
and reduces quiescent current to <1μA.
The HX4004A is available in the industry
standard SOT-23-6L power packages.
