Description
- Typical Application Using LTC3612MPUDC General Purpose Buck Regulator Using Ceramic Capacitors, 2.25MHz. The no-load DC supply current in sleep mode is only 70 uA while maintaining the output voltage (Burst Mode operation) at no load, dropping to zero current in shutdown. The 2.25 to 5.5V input supply voltage range makes the LTC3612 ideally suited for single Li-Ion as well as fixed low voltage input applications. The operating frequency is externally programmable up to 4MHz, allowing the use of small surface mount inductors. For switching noise-sensitive applications, the LTC3612 can be synchronized to an external clock at up to 4MHz
